340X heads vs late model LA heads vs Magnum.

Does not compute... The quench gap will be there whether the piston tops are at zero deck or above deck. Just set it with the head gasket thickness. We have piston .005" out of the hole and a .045" thick gasket for a quench gap of .040".

dont see anything where he says the pistons are .005 out the hole...what if they are .020 out of the hole...so until he pops the heads off and measures the deck height...any guess is good as mine...

4.30 gears with 31 inch tall tire.....i would add more gear with those tall tires...
