Hi Engine builders,
Looking for the guys that have experience with using 3/8 pushrods in the RHS X heads. I am using the PRW 1.6 stainless rockers with valve lift right at about 605 lift. At max lift the clearance on the exhaust side is minimal .003. The intake pushrod hole comes up further to the valve gasket rail, and the pinch is even tighter. Has anyone run into similar problems? The angle from rocker to lifter creates the clearance issue closer to top, and then it opens up closer to the lifter. slight rub bad? If so what's the fix? die grinder or machine shop to recess (open)the holes up top?
Thanks for any help.
T.J.
