Edlebrock recomended that I run 1.5 rockers on there heads and use the cam with the lift that I want.
I have been running 1.5 Crane gold roller rockers on both of my cars with RPM heads for 15 years on my 340 and 6 years now on my 440. No trouble ever. I ran Crane gold roller rockers on several 572 chevy motors with roller cams that I drag raced in a dragster with close to .800" lift and never had a failure either. Ran 6.80s at 200MPH with it.
