Hey guys, i just bought a set of Comp Cams 1.85 ratio roller rockers, guide plates and studs off ebay. I just want to know what else i will need to install these. Do I use my stock push rods and lifters? Will my springs be too weak, is it absolutely necessary to change to a stiffer spring? I posted this question before but didnt get much help.

Is every thing in your engine stock?

I believe the guide plates will destroy your stock pushrods, so you need to get some hardened ones...lifters should be fine with stock cam.

Jorge Olmos

Yes Sir. You should get their push rods and their valve springs and retianers
I do remember when SLP sold their 1.85 rockers they required a valve spring upgrade

At the very least get the new springs. Our stock springs are barely enough for the stock cam. If not, you'll almost certainly get valve float or worse.

Springs and pushrods. I would stick with the stock ratio though honestly.
