Rocker design for P51 heads.
Which of the stud mount rockers fit the best on P51 heads in a solid roller application about .8 lift? I'm considering the Crower stainless steel. Would the 1.8 be any problem, to get a little more out of an existing cam.

Randy Moore's 562" engine had 1.8/1 SS Crowers on the intake side.....seemed to work good.

Did y'all use the crane on his exhaust for a fitment issue? Was there an issue with the crowers?

Comp 1830-16, (Ultra Pro Magnumâ„¢ XD) here on my P-51s now.
I had the older Comp's and the rocker body didn't have enough clearance around the adjusting nut to allow for max lift. Rocker body was also close to the retainer as well.
The blue FRPP's (Crane) I had on there the first time fit with no issues as well.

And they are 200ish cheaper than the Crower. Thanks for the help guys. Should have a new p51 headed 557 in the next few months.
