OK I'm installing the Edelbrock Heads and Erson Rockers, on the 428, Crane H-296 cam. What do I do to check the Valve train geometry? The push rods are contacting the Performer RPM near the top of the intake, so I will clearance the holes some, but the holes look close to the ports.
Help.------------------

Glen,
You wrote;

Are you using guide plates? Happy Thanksgiving to Nancy, Brian and yourself! See you Sunday at the track.  SteveW

Pushrods go through the Intake on an FE Steve.
You guys too
May or may not go to the track on Sunday could be on a roll with the install.
Did you get the rear installed? ------------------

You don't need more than .020 clearance Glen. You should be able to ream the intake with a drill bit easily.
Steve, on FE's the intake is 1/3rd the cylinder head on the intake side. They have holes cast into them that the push rods go through.  ------------------
