I'm assembling my 408 stroker (4.030 bore) and now that I have the pistons installed, I measured the deck clearance at .020" I have Trick Flow powerport aluminum heads with 60cc chambers and Mahle pistons with 16cc dishes. This engine should put out about 525/550 with the cam selections and the rest of the package. Wondering what head gasket and thickness would be recommended and why. I should be running about 10.7:1 compression depending on gasket thickness. Do you think I'll have an issue with pump gas? We have 91octane around here commonly. Thanks.
