I am in need of some advice. I am checking the push rod length for my set up, flotek heads, felpro .037 head gasket, and summit roller tip rockers for fulcrum type rockers. I am full bottom on the cam/lifter lobe. Marked the top of valve. Adjusted push rod checker till it touched then half turn on poly lock. The pic is my first go around then I got the mark in the middle. I wound up with 6.200 for a final length with a centered mark on the valve. Anyone else have a similar set up?

Looks like you need about a 6.150 pushrod to get the roller tip centered on the valve stem. That should also narrow up the sweep across the top of the stem.
