Call Bob at Modern cylinder heads at 568-468-7914 and talk to him about doing the CNC porting on those 440-1 heads like he does for a lot of the big name Mopar engine builders, maybe even for Indy before they got sold to the new owners.
I've had them do, CNC port and valve job afterwards, several sets of heads including Brodix B1-BS , Eddy RPM ,Indy SR and Indy 440-1 with good results
Ask him about changing the intake valves to the 2.250 also at the same time
