Im reading many different things about the Edelbrock RPM heads in regards to stock rockers and pushrods, I thought they were an exact copy of the physical size of the iron units.


I set the roller rockers when I had the vally pan off and was able to physically see the lifter on the cam, Im thinking of re installing the Hughes Rockers and pushrods and trying to adjust them again but Im thinking it may be difficult not being able to see the cam and lifter?


No it's not that hard though it does make it easier, I have set up a couple of engine that way. The last 2 I did I used adjustable pushrods with stamped steel rockers, so I could set the preload exactly how I wanted it, because not every valve is the exact same height due to casting variation of the heads.

Also note that some .904 lifters are also made to fit AMC applications and those lifters the pushrod seat is .200 taller, meaning you have to run a shorter pushrod. This was also the case on those 2 I did as I used Crower cam savers which are AMC spec. :crazyme:

If you want give me a call and I'll swing by on my way home and give you a hand.


running up my post count some more .
