Usually those heads would have raised numbers on them. Any idea as to what those number are?

all 6 cyl, are 70 psi hard to bleave a engine that big would have so low compression how do they get 200hp out of that sure dont sound likley

I wasn't asking about compression numbers. I'm asking about the actual 6 digit numbers that would be imprinted on the heads. These are usually cast numbers that are raised rather than being cast into the metal.

If on the off chance, you are looking for different heads rather than what your engine normally incorporates, what are the part numbers of the heads you're looking for?

That engine should have 100-110 lbs. compression. Mine has 90-95 psi right now, and I consider it to bee too low.
Your low compression is not being caused by heads.

Bee your engine has the later model heads so it will have more compression, I will get numbers off my heads tonite. Just install the new style and you will be ok .

The small bore heads will have numbers ending in 1490.

Like we talked about before, you need to define why you think you need to do this. It may not be benificial anyway. Those big bore GT heads are pretty good ones.
