The lifters have nothing to do with the push rod cup. Lack of oil is the only thing that can cause that.

I have Edelbrock's with 56cc chambers. I am going to run E85, so running the .045 Cometic MLS head gasket would give me a little more compression. If you suspect I would see piston to head contact with .036-.037 clearance I would just get the .051. I wish they made a .048. JimActually, I think you will be fine with .036 quench. I was asking because some specs on production head gaskets aren't accurate but, I'm sure the Cometic specs will be accurate.
