Best Rockers for Indy 360 heads

Too much cam for a non roller rocker. You really dont want to "scrub" the rocker tip across the valve with a super aggressive solid roller cam, it will wear out the guides in a hurry. And if the iron rocker does not have some sort of bushing it will not last with high spring rates(over 400#), as the iron will gall on the shaft. I have seen them weld to the shaft before, MP or Crane.

Plus you are not going to get a full fluid wedge affect if you dont convert it to full time oil under full pressure. Mopars have timed oil "squirts" and dont built full oil pressure in the rockers.
