So I'm considering what gaskets I'm going to use when I do put the Speedmaster heads on..
Being .010 above Deck with flat top pistons with valve reliefs I'm definitely going to have to be in the .045 minimum..
Right now I use the fel pro 1008's at .039 with 596 heads that I just guesstimate at 70 cc's.
From the calculations if I use the .045 I'll probably gain a half point of compression.. witch is not going to help me try and get back to pump gas only witch is one of the two things I was hoping to gain the other being weight loss..
So I'm thinking a .060 gasket... This should keep compression close to the same, a little safer clearances, and hopefully the heat conducting characteristics of the aluminum convey the ability to run pump gas instead of having to add I little Sunoco to get it to turn off..
Current set up calculations...
