Curious if anyone has real world results of putting the old TR590ps (not ps2) intake sides on stilts? It's going in a 117". It'll only be running 200ccp (10.6:1) so I'm wondering if the extra lift might help the bigger motor? I know most run this at 10.8-11:1 but it'll be touring quite a bit.

These heads are 96" castings and have .650" beehives. They've pulled over 140tq and close to 140hp, so they're capable. Rush wrath pipe, SE 58 w/5.3

Cam specs:
Intake 22/44, 246°,.590",  Exhaust 48/20, 244°,.590
