Cylinder head discussion 340 with stock above deck pistons

I think u better check your math. If your piston is out .054 u could never even gat the head on with a .040 gasket. Kim


My math is fine. I wasn't talking about using a closed chamber head. I think the OP asked what Chrysler said about how far they should out of the deck.

I think (I can verify when I put my turd back together) with a .039 gasket and being .054 out of the hole I have .040 quench which means the chamber relief is about .055, which when I typed it seems less than what it is. Maybe I'm .060 out of the hole.

But the math is something close to that so the head will go on.
