Mopar Got Heads

We have the Edel. Heads on a bunch for our Bracket Stuff.......Routinely down to 75 CC. The spec is 73 on the Early Head I think and should be
no sweat to make them that Jim. I think early 383 are neg deck flattop so should be fine on piston to head. Later ones (68-69) with positive deck might have to give up a little on deck or run thicker than spec Gasket...., but should be only 010-015 at most. Piston to valve might be a little tuff with no valve relief (As in Sink your valves a bunch).....If you need more info Jim PM me
I know the fix.

PS: Doing much Better!!
