Just pulled the engine apart during my resto and came to the unfortunate realization that my head is cracked. I'm thinking about buying a 2.2 Laser first gen parts car....will that head work?

Your gonna want a 782 'swirl' head. Pretty common. How/where is it cracked? It is very common to have cracks between valves in the combustion chamber area, and most are still ok to use.

From the other thread, we'll move this over here.:thumb:

Between the valves is very common. As long as it isn't into the water jackets your fine. But if you need another head, they are cheap and plentiful.

Where are you finding cheap and plentiful heads?

Junkyard's around here average $40 for a head and usually have about 15 cars with them.

A friend I've just spoken with, a TD enthusiast, says our yards only have TD's with busted heads. Doggone!

I find it hard to believe that they ALL have bad heads. They WILL crack between valves, but if the cracks don't go all the way to the water jacket then your fine. If the head pressure tests OK then use it. All of mine have cracks in at least one chamber.

an 84 is a early G-head. an 85 is a 287 G-Head and anything after that is a Swirl head

how about posting some pictures of the cracks in the head. You never know, they may not be that bad after you let others see what you have.

:amen: We're all a bunch of crackheads around here. Cracks between the valves are common, it's hard to find a head without them. Cracks from crossdrilled coolant passages to the water jacket are also common and nothing to worry about.

Cracks from the combustion chamber to the coolant passages are the ones that I would be concerned with.

200 for a reman head isn't bad, i will usually spend that much just getting a stock head redone at the machine shop. chances are even if you get one from a junkyard it may still need to be checked, resurfaced and may need valve work and new seals at least.

Yuck? I don't mean to come off strong but if your upset at spending $200 on a head, you shouldn't be playing with turbo cars, ;)

An 86 Laser will have a swirl head like you have, but it will not be cross drilled and you will need to swap the cam. Like Xtrem said, 84-85 Lasers use G heads.

I'm with Simon.

Beautiful bolt it on and go head, just make sure it has turbo valves.

I'm not upset...I just think it sucks that something I thought was good is something I have to pay $200 for. I was under the impression just my HG was bad...thought wrong I suppose

Did the shop pressure test the head?

yes, pressure test, and post pictures.

Like was said before, the head may be normal, but we cant tell with out some pictures.

I'll take some pics as soon as I have the time...work has been absolutely INSANE the past few days. Oh, and it wasn't removed by a shop, it was removed by my husband, an ASE certified mechanic.
