Did you check the CR before assembling? This is a MUST. Probably your heads have been flycut, maybe multiple times, so the push rods are now too long. I've seen some cross-sections where heads have been flycut so far that the fins are about to fall off. If it's a really bad job, the flycut surfaces aren't in the same plane, so one or the other(or both) barrels won't seal, result is massive compression loss and you get to do it again real soon. You'll need to calculate how much additional thickness you'll have to have and get some barrel shims. I have seen and had some heads off wrecks that had shims in the heads, this is not the way to go. Also, both sides have to have the same CR. There's a lot more to rebuilding than just getting some parts and throwing them together. Gene Berg's technical articles have lots to say on the matter. If you don't get the correct valve gear geometry, you're going to have troubles, there, too. On Tue, 15 Jun 1999 09:33:40 -0700, you wrote: >I too, have a sad tale to tell.
