WTB- 655 G head

[moparzrule]

Looking for a 655 casting G head. PM me with a price shipped to 17015, thanks.

[moparzrule]

bump.

[Xtrempickup]

Any particular reason for a 655 ?

[moparzrule]

Just wanna try one out.

[Gold85GLH-T]

I have a g-head. I'll see what casting number it is and let you know. It was the original head on my 1985 omni GLH-T if that would narrow it down?

[GLHS60]

They originally came on 1981 and 1982 only, and had an oversize intake port, and are the only head where the intake gasket matches the intake port. All later heads have an intake port smaller than the gasket. I'm sure moparzrule knows this, so I'm just posting for general info. in case someone has one laying around. The general consensus is they are no good, but I also have one that I'm hoping to try once my intake is finished. A few guys who ran them seemed happy so the general consensus might not always be right!!

Thanks
Randy

Nah that'll be a 287 casting, thanks though.

I have a ported one sitting in the shop to try on something also :) With the correct intake I think they will make some good power, probably not as much low end as the smaller ports but I'm thinking top end will scream. The few who have run them and describe how they run seem to support this theory. Boostgeek said his would pull 8k no problem. His had large valves also, as well as 2.4 lifters.

[Xtrempickup]

Going yarding sunday, il look for you.

[moparzrule]

Yeah I'm going tomorrow, but I'll post if I find anything or not. Thanks

Right now on a 2.2L I'm running a 57 trim with stage 3 .63 turbine, TU header, ported 2 piece intake with 52mm TB, and a ported +1mm swirl. Also planning on trying TU's R2+ cam with this setup. Eventual plans are the Acannell intake, 58mm TB, HE351 holset, and a ported 655 head. This car is not a daily driver, just a weekend cruiser, so all high end power is fine with me it helps with traction anyway.

[Xtrempickup]

Post if you find any or not.

the ports on a 655 are the same size as 2.0/2.4 16v ports.

[4 l-bodies]

the ports on a 655 are the same size as 2.0/2.4 16v ports.
yeah, and Ford 429 CJ ports you could about roll a tennis ball through. Big ports mean about nothing if the rest of the design can't support it. The 429CJ hardly rewrote any record books. Exactly like the 655's legacy (lol).
BTW what is the volume of the 655 intake/exhaust port? Anyone know besides bigger than a 287?

[Dr. Johny Dodge]

only thing wrong with the 429 CJ heads is the exact same thing wrong with the standard 429 / 460 heads

the CJ intake ports are good for high rpm big block ford - the standard port not so much
BUT the exhaust ports suck
they turn downwards inside the head to allow an exhaust manifold that fits stock applications

but , raise the exhaust ports 3/8's inch and the head turns into a freeking monster
aka trickflow heads for 460

horsepower on spike's power block did a "stockish" rebuild then to compare they droped in a 688 lift cam and the T F heads & intake - made close to double the power

lol I've got the short block and the T F intake - I stalled out on my 460 when I bought a computer and discovered TD and TM.... still need the ### heads but I keep buying turbo 2.2 stuff

sorry ... I tend to stray at mention of BIG FORDS

My '85 Omni GLH H.O. had a '445' head on it. What is the difference between the '445' and the '655' or '287'? I thought they were all G-heads.

[moparzrule]

85's usually had the 287 head. Basically and typically, 81-82 used the 655 head which has the largest ports of all the stock heads. 83-84 was the 445 head, normal size ports and used 10mm head bolts. 85' used the 287 head usually, same ports as the 445 but 11mm head bolts.


Xtrempickup- I struck out today, found a couple 287's and one 445. I saw a dodge 400 and my eyes sparkled but when I got up to it it ended being an 83' so it had the 445 head. :( That 83' was the oldest car there at Harry's U pull it.

[Xtrempickup]

Did you go to new ringgold ez pull?

[moparzrule]

Nah didn't have time, needed to get home.

[Xtrempickup]

Well im headed to both again. I got odds and ends to pick up. Mostly stuff i just dont wna buy new

[onerippinturbo2]

it's been awhile since i've been to ez pull n save, the last time i was there there was an older rampage, but it had a 455 head on it so it wasnt that old lol. i planned on hitting up a yard this past saturday but the honey do list pulled rank.

[Xtrempickup]

Nothing older there but that rampage. Nothing but 1 t1 log car there. Least 1 523 trans. 1 525 5spd omni. 1 daytona non turbo 91 body. I was able to get things i needed at ez pull. I need to find out about that other yard there they own in meyerstown i think thats also a u pull it according to their website

[GLHS60]

There is one on ebay now, $90.00 buy it now, bids starting at $50.00 Not mine.

Thanks

[moparzrule]

Hmm, thanks but that head looks pretty fishy.....they say it was surfaced but it looks more like it was just went over with a conditioning disk, and that valve job looks very suspect. Just look at how far the valves are down into the seat, not good! Since I'd be going large valves I'm not worried about the valves, but they may have fubar'd the seats too. I haven't decided if I'm going to go with oversized seats and the extra large valves yet, I might just do that if I pick this head up.

Funny this is that it has a roller cam in it, so that gives it a little extra value. I might just wait until the last minute and bid, if I can get it for 100 shipped that's not a bad deal.

Thanks

[Xtrempickup]

that head has roller followers? wouldnt that head be a slider cam head? Are the correct springs in it now? Lots going on. No pictures of the intake ports or exhaust ports

[moparzrule]

Yeah that's what I mean, very fishy for sure. I wouldn't count on anything being correct, but honestly I'm only looking for a core head to port/rebuild myself. New guides, springs, locks etc but I was only going to use +1mm valves so the seats still have to be in good shape. That's the only thing that really concerns me about the head.

[Dr. Johny Dodge]

deck surface looks like it got a go over with a sanding disc in a drill
none of the intake valves are really nice but #1 looks like it's missing a chunk out of the edge at 8 o'clock

front center oil return hole looks like a chunk got taken out of the edge of the hole
looks kinda like it got put down on the oil dip stick bracket that goes to the t stat
if so it might have a nice leaky dent in the surface too

[guyd_15]

Got one in my garage. It's one of the very first setups. It's even got that setup with pulleys on both ends of the cam. It's unmolested Sliders are all there, no port butchery, it's in top notch condition.
You wouldn't believe how many people think I'm nuts when I tell them a 2.2 head had pulleys on both ends of the crank.
Check your PMs.
Guy

[moparzrule]

I did not receive a PM, please resend :)

You can ditch the cam/rockers and everything external on the head to save weight for shipping. I just need the bare head.

[Dr. Johny Dodge]

guyd_15 your pm box is full

I wanted to express interest in that rear pulley and the bolt for it to mount to the cam if you gut the head for ^

Difference is the 665 isn't as good.:D It's not a huge runner, also... just at the entrance with the expense of having really poor short side radiuses. You need a certain balance of taper and cross sectional area to where it "necks down" for ultimate velocity for the engine's particular needs. I flowtested a stock 655 vs a stock 445 years ago, and posted my results along with cross sectional views of the horrible 90 degree turns on the short side's floor.
