Re: roller rockers

Springs are going to be determined by the cam you intend to run. If you don't intend to run anything other than a stock or LT4 hotcam, you can use the LT4 springs and should just get the LT4 hotcam kit from summit or somewhere. Otherwise, it depends on application. You'll also probably need some new gaskets. I'm going to be doing this soon as well and putting a list together. The search function is your friend.

Re: roller rockers

but if you have ANY intentions of anything bigger than a hotcam do a spring upgrade that can take up to 0.600" lift, you will never know the future and to do a valve spring swap x2 would suck.

Comp cam has a great selection of rockers, if not going to a crazy set up, self aligning rockes with a 3/8" stud would be fine. ARP studs prefered.

Re: roller rockers

thats a big cam there, .570" with a 1.5!!m thats a .608 with a 1.6 rocker, so I would say comp cam 918 springs, I use those with my cam good to up to 600" Mine is a little higher and no issues.

Re: roller rockers

on stock heads, 7.200" pushrod, the applicable retainers and locks will be needed, steel is cheaper than Ti.

I am not sure about the shims or locators, i didnt do my spring swap. But installed height should be checked in each spring
