"Squish" problems

Looking back, it was a mistake on my part to assume that a compressed "Mercury" gasket would be the same as a compressed "Fel-Pro". My problem is coming back from this situation.

Hi Den, you don't say which Fel-Pro part numbers you are working with but most of our builds get the 1055'/1056's (for the later Flatheads). If these are the same numbers they measure .062", fairly "thick"!!

We also use the 7525B-1/7526B-1 numbers when the others aren't readily available, same gaskets mentioned above, different packaging/pricing?

I would give all here a "tip" when checking P/H clearances, install the heads (both sides) without any head gaskets and make certain the crank/pistons rotate with no clearance issues. If it turns without gaskets (most times) you will be good to go. On some rare occasions it may require looking closer at everything but generally speaking it will be good.

Thanks, Gary in N.Y.

P.S. On a side note here, that compression number seems a bit high even for hi-comp heads?? Also that earlier offer still stands on the heads!
