Guest Russ240z Posted March 12, 2002 Share Posted March 12, 2002 At what point do you need them? Example... If I keep the iron double humps (pressed in rocker arm studs) I have with .507 lift cam and 1.52 Comp roller tips, do I need the guideplates? I'm struggling with the $1200.00 price of new aluminum heads. I just want to explore all of my options. Quote Link to comment Share on other sites More sharing options...
biohzrd Posted March 12, 2002 Share Posted March 12, 2002 with that much lift i would suggest guide plates and screw in studs. when you get into lift that high the press in studs have a problem with pulling out which is never good.make sure that your springs are also up to the challenge. although your valvetrain has alot of pieces to it they all have to work as one unit. otherwise you will not get the full benifit of a bigger cam Quote Link to comment Share on other sites More sharing options...
