My push rods were 7.425 as I milled my heads .020, thus the difference. I’d assume GPI will give you 7.400
My build thread shows all I did (start @ page 5)...

Agree with Don, the VVT oil pump is a stock high volume unit, due to the AFM lifters. Keep us updated....cam & valvetrain upgrade is next on my list & very interested in installing a GPI's SS1 kit w/DOD delete also.
