Performer pedestal heads
Comp 1.7 cobra lifters ( non adjusting )
Right now I have comp cam 6.248 pushrods (what jegs customer service recommended )
I tried the adjustable push rod thing but if I adjust all the lash and the lifter starting to collapse the marks are still riding high. Confused !
you should have a set height for the vulcram on the roller rocker. you need to find out what that is , contact the manufacturer if you have to.
then get a adjustable pushrod. you can use the adj pushrod to get the length set perfectly. then measure it. that will tell what pushrods you need to order.
just to be sure you tightened the rockers down in the proper firing order?
