Wheww.... Lots to do, decisions to make

So on top of replacing the entire valvetrain in the AFR heads, I'm looking at figuring out my compression ratio.

According to all the measurements that I have, the motor currently sits at 10.49:1 CR. This is with stock 53cc heads, .020 (in the hole) pistons, and I think a .041 head gasket.

The AFR heads are 65ccs.

If I angle mill the AFR's to 55ccs, and use a .026 thick head gasket, I'll be right at 10.7:1 CR. I can't find a steel shim that will work for the LT1... If I could find a .015 thick shim I could bump compression to 11:1......but I'm hesitant to run that thin of a gasket.

Has ANYONE hear bad or good things about Mr. Gasket MLS style gaskets? I found a set of 4.1 X 0.26 Mr. Gasket head gaskets for a real good price. I've only ever ran fel-pro or cometics. I know cometics would do the trick but 100 bucks a gasket is a bit steep, and the finish on the deck and heads has to be just right in order to get them to seal.

Hopefully I get this pig done by Automotion LOL

Okay, never mind. I'm going with custom made cometics. Should be interesting.


Fuck me I'm confused right now LOL

I've never done anything with v8's but I've never stepped outside of Felpro/Cometic with any of the engines I've ever built.
