In a recent purchase i think i just realized that i bought 3/8 1.6 self aligning rockers, im gonna have to change pushrods to use these arent I? Iv got a cc305, EX612 valve springs to go in and then those rockers. Am i gonna have to change push rods and which ones can i use or what else would have to change to make these rockers work? Any help would be appricated as im supposed to drop the car off at the shop wednesday.

 

no, the stock length pushrods will be fine with the 1.6 rockers.
You do mean the stud size for the rockers is 3/8s and not the pushrod cup right?

 

I think you want hardend pushrods to handle the stress of the new rockers. The length is fine, but the strength isn't. They stopped putting hardened pushrods in the LT-1 in late 94.

 

If youre not running guideplates and your spring pressure isnt too radical (much over 350# open) then regular pushrods will do.

 

Nevermind, I see you have self-aligning.
