470 going to the dyno - HP/TQ estimates

Indy SR Heads ported by Indy to flow 351 CFM @ .606 Intake and 233 CFM @ .606 Exhaust
Holley Street Dominator Intake that was extensively worked on

Are the heads and intake still std port size, or opened up closer to MW size?

My suspicion is…….the HP will peak around the point where the lifters start to get unhappy.
