Smashing sounds like the most productive solution...

That is EXACTLY what Justin and I were talking about. This thing seems to be cursed! I am even a little weary letting it sit in my garage!

I think the heads warped from the fact that it didnt fit on the ARP's, the coolant, and the low compression on a good block.

My attempt here is to cut down on miss information and to maybe head off a witch hunt aimed at a poor little cylinder head.

The ARP head stud fitment is a COMMON problem for any head good or bad. They just get stuck at wierd angles some times.

Again, a bad cylinder head will almost always cause NO compression in a particular cylinder or two, because if a whole is open it's not going to hold any pressure.

The coolant on the other hand...that's another story. It's not actually one I've read about on this head before.

Either way if you want to smash for fun go for it, but it may be a perfectly good head or at least repairable for a small amount of money.

You think it may have gotten warped along the way somewhere then Marcus? Ovbiously Mark's motor is ok, otherwise he wouldn't have been getting 170 psi before. Not asking anyone to speculate, but perhaps having it re-milled would fix the problem? I've heard that it's possible to warp a head just by not removing the head bolts in the right order... possible culpit here?

Ive also heard that you have to remove the bolts in the proper sequence. I followed the haynes manula VERY carefully when installing and removing both heads. Is it really not as important as I had thought?

And BTW- I was totally joking about smashing the head. I would think it would be saveable if it were warped by milling? And deffinately saveable if the valves were seated improperly.

From my experience a bad head or valves will result in very very litle or no compression at all.

Not to start a dispute but to add my 2 cents, that wasn't the case with my fwd when the intake cam gear cracked and I bent intake valves. I still read between 60 and 90 psi of compression on each cylinder with a bent valve or two. That may not be the norm though.
