Rocker arm recommendations?

Not quite. I’ve narrowed my choices to the PRWs, trying to decide which ratio I want now. The rotating assembly in this 440 is a copy of your Pops 440 build. The top end is a set of 84 Cc chambered RPM Heads. Cam is a comp XE285HL flat tappet.

That's already a high light grind. I don't see a need for the 1.6.
