I’m looking at moving to a new set of rockers to add some ratio / lift to make better use of my heads. My current rockers are bronze bushed units, I’m looking at a set of needle-bearing roller rockers. My assumption is that this change at the shaft would release a ton of oil pressure. (Correct??). Do I need to install a restricter somewhere? Walk me through this please.

Engine currently idles around 45psi and runs at 70psi, 80 at higher RPMs.

Thanks-
