Dead on. I measured mine out to right at 53cc's.

Think I'll be going with +1's for this head. I probably won't take it as far as the scribe marks. I'm debating on tossing the first head on there and run it or port this one and use it. Only problem...

Using the ole eyeballs I think it's pretty similar to the one Todd posted in post #91.

Getting started on another head I have. What do y'all think about my scribe lines? Too far, too close to the valve?https://drive.google.com/uc?export=download&id=1Zi3nuPypSGSLM0JiC5-TlgTu-n_CZvPl

Thanks for the tips. Between you guys and the hours of YouTube videos I've watched, I'm learning a lot.

I just realized my phone has a super macro mode and does close pics pretty good.https://drive.google.com/uc?export=download&id=1YSMojDOrfKYOrsdB73kdx7014OX_9NRL

Oh yeah. That bit is tough. I do have a set of junk valves I used that I ground thinner to make it a little easier to grind around them. Pic might not show it good enough but I tried to radius the...

Seats are just dirty and/or metal dust on them. That's the hardest damn part though. Not hitting the seats.
You mean radius this...

Well, more or less done with my first ever attempt at porting. Thoughts and criticisms? https://drive.google.com/uc?export=download&id=1XetONteNzyJr6MAb1-HYCEEh7wr9mdOo

The Dremel is great for getting in the small areas that need just a little touch up and when you need more precision. This particular Dremel maintains the same RPM regardless of load. The blue point...

So far, these are my weapons of choice. The bit that's on the die grinder will chew through aluminum in short order. Literally minutes to deshroud the valves...

Todd, how much does you typical swirl chamber job increase the chamber volume? I ordered a cheap volume checker but I'm just curious. What's the volume of a stock g head and swirl head? Dodge garage...

The sensitivity part is why I didn't go crazy. Just as easy to make it worse as it is to make it better when you don't know what you are doing. I definitely fall into the don't know what I'm doing...

Already did the ports. Just kinda cleaned them up, smoothed them but didn't change shape really.

More or less my completed chamber. Now that I know what to do it'll take me a lot less time to do the others. I don't understand why it keeps posting the picture sideways. Annoying....

What diameter and grit cross buff do y'all use for the exhaust ports?

My ghetto way of getting them close to the same.

Here's a look at a CNC ported ls3 chamber for reference. Obviously not 100% applicable to our heads but it has some similarities with a 782 chamber. Would not look much different if the hump next to...

Up to this point I have done everything with a corded Dremel. Not ideal to say the least, but it works. Problem is you can't really use long bits. Then I remembered I already have a die grinder so I...

Stock, it's kind of a straight line. I more or less grinded just enough to get a radius. This picture I posted on the first page of the thread is what I'm basing it off of. Ken aka 5digits posted...

Started trying to port my head.

Cleaned up short turns and throat....

Nah. Haven't done that yet. I'm going to port a head myself eventually. When that day comes I'll do something similar and also do a turbo blanket. Although I've read the turbo blankets don't last all...

I thought about that, but I'm lazy. I just eyeballed it best I could while looking through the TB opening on my lengel. When I pull the head eventually I'll probably do that.

Sure did. I did it a while ago. Stuffed rags in the ports and sucked out the dust with a shop vac.

I gotta get an actual tool. I port matched my 2 piece lower to my phenolic spacer with a Dremel and that was a nightmare LOL.
