Pushrods And Trick Flow Heads

I'm running prw 1.6 stainless rockers as well, with 3/8" pushrods. Hydraulic ft cam (around 0.600 lift, measured) with lunati microtrol lifters. Clearance to the pushrods is tight, I really had to triple check my rocker shims because being off 0.020" was enough to cause concern. I had one rod rub during breaking, but only just barely. I re-shimmed that rocker and haven't had a repeat.

If I were to do it again, I'd go solid ft and 5/16 pushrods.
