22 cu inches great idea with the offset grind
Your heads are going to determine your top end hp and I would not count on much increase there however below peak torque should be greater as you can work the heads to the max at lower rpms
The jones inverse flank rollers run like 4-8 degrees larger than they spec
so otb i would make no changes
Did you have Mike run the numbers- I'd install it wherever he suggests
Theoritacally the extra compression, although minimal could suggest a wider lca but I'd not do anything till you run it and maybe move the cam around a little- whatever Mike suggests. rod ratio and crank throw also change requirements
it's complex- so run where you left off and go from there
Have you plotted your piston to valve at different timing (icl) with the new pistons
I'm sure you know this but with those asymetrical lobes timing of the max lift icl is useful only of you figure it out in relation to the seat timing you need to be timing from seat timing icl
