Pushrod Clearance 1.6RR Vortec Heads

2 Attachment(s)

I am in the process of converting my 350 TPI to ramjet intake and vortec heads. I installed a ZZ4 cam and modified "ZZ5" vortec heads with 1.6 RR Comp Cams Pro Mag Rockers. The push rods are 10241740 new GM Performance.

Per the pictures, I have very slight clearance. Do I need to elongate the holes, or is this enough?
