I just looked up your cam profile in the Comp Lobe list book Is that a catalog grind or custom?
That is a really quick cam
I definitely would not use the small roller without an OK from comp
1 If roller rockers have you shimmed up your shafts by about the amount of the radius of the roller- there are currently some good pics of the difference it makes
2 correct wt oil
3 Tried beehive springs and/or TI retainers
what are your head flows, compression, stroke and rod length
hate it when this happens
cheers
