i need a little 340 help. Lets Talk head gaskets

I'd just have the pistons fly cut to fit the heads to get good quench. Yes it means re-balancing but throwing thicker headgaskets on can cause other issues as well.

Does your build require 12.5:1 static compression?

i don't require 12.5:1 compression just want to use the setup since my dad ran this combo a long time ago. Yeah Little worried about the intake gaskets with the thicker head gaskets. I'll see if i can put the J heads on to see if they fit with the .040 head gaskets then make the decision.
