As I said before ... seaBee had some good suggestions.

I did some figuring some years back and DID FIND my first piston option and that was a set of std bore 426 max wedge 11 to ones

SHOULD be pretty close to perfect with those industrial heads at almost ZERO DECK ....and fantastic quench BECAUSE it’s a closed chamber head .....

BUTTT that closed chamber is something like 110 cc !
