David Vizard, Uncle Tony's garage, Unity motorsport. Mission impossible Dodge 302 Head porting

Well this is not my area of knowledge, but the way I read the table in the DC Engine Book, the -.040 is the piston down in the hole.
So with a .020 gasket and 59 cc head a standard bore will be about 10.2 CR
Estimating with the .030 gasket closer to 10:1 CR

Yeah we are real close, for sure at least 9.5:1 cr.

If it is closer to 10:1 all the better.

It goes like a son of a gun, so yeah I am liking that number 10.

It breathes real well too. Stock size valves, no port work. Only gasket matching the heads to the intake and making sure there was no step going into the stock A Body exhaust manifolds. That LD4B intake is a piece of magic that is key to bringing it to life.
