So I'm running the new 21* Trickflow heads. The valves on these heads are spaced slightly farther apart than a stock head. My pushrods come out from the lifter to through the guideplate notches and to the rocker arms at an angle, thus slightly turning the rocker arm so that with each pair of rocker arms, they are not parallel with each other. They are sort of like this:


/ \ (Exaggerated). The pushrod also rubs on the guide plates. It appears a little material needs shaved off the guide plates.


Anyone else running these heads ever have this problem?


Thanks in advance for the help.

I used Isky adjustable guide plates, mocked them up and torqued the studs. Once everything was adjusted where it needed to be after being torqued I tacked the plates together. That's what AI suggested to me.
