I'm looking at thin head gaskets in the ~.028 range and I found a few, GM makes one (10105117), mr gasket has one (ultraseal 1134), and victor reinz 5476.
These 3 all seem to be a bit fancier than a plain shim gasket, but how flat do the mating surfaces need to be? I have a 1977 350 block thats never been decked and a set of vortec heads, I'm not sure how flat they really are yet. Anyone have experiences with these?
