    Poly Locks on 3.4 Camaro Rocker Studs

    Need help.
    What are you all running?
    I have stamped Steel Comp roller tip 1.6 rockers.
    Will Poly locks fit under the stock valve covers?
    I upgraded to ARP 100-7201 rocker studs and ARP said that I NEED poly locks.
    I have the 1.3" part# which was recommended - discovered tonight they don't fit.
    Should I try the shorter ones- 4601. Those say for full roller rocker arm though..

    If ARP said the 100-7201 fit and they didn't I would question why I was running their product...
    I'm a thousand miles from no where...

    Anyone else want to weigh in.

    So what do you all run with 1.6 roller rockers with a bigger cam (224 224 with about .52 lift)

    stock rocker studs?

    ARP studs fit but the locks ARP doesn't make- the cam companies seem to. So ARP punts to Comp Cams to make that decision.

    I think I'll go with the Crower part # I found - 86051S. These are much shorter and should work.
