Dear Doug;
You'll want to go ".060 over" on your 292 using Ross pistons creating the compression you want and just 'clean up' the deck.
That company (Ross) makes a precision product that's first rate.
You'll want to 'shot peen', polish and ballance the rods & crank too.
Just do it in stages as the money comes in and then you'll have the foundation for "what if".
Good luck.
