What Rocker Arms Are These?

The earlier Comp rockers(prior to them being bushed) came with the recommendation of 350lbs max open spring force.

I’d also use high zinc oil.

I did have some issues with the unbushed rockers and roller cams using springs that had about 525lbs open force.
Actually, now that I think of it....... one of the problems was with a SFT cam application and just under 400lbs open.
BUT, they were running gas mileage type Mobil 1.

This is great info. Thank you sir! I wonder if Rocker Arms Unlimited could install bushings. I'm thinking it'd be cost prohibitive though. I may call them tomorrow. If it's too much, I may just sell these and put the cash towards a different set.
