    Oh so no noise at idle, or if you just rev it up ??
    I thought it was at idle, and if you rev the car up in neutral.
    So no load, no noise ??

    Guide plates only help side to side motion with stud mounted rockers. Won't do much of anything for a pedistal style mount rocker.

    Can you get a sound file for us? Knocks are bad, but ticks are generally ok, but sometimes a sign of something wrong.

    Is this better than doing a PCV delete?

    its comeing from the driverside head area i was thinking it may be the lifters because it is alittle bit louder when you move the srewdriver to where the head and lower intake meet.. when i use the screwdriver and check on top the valve cover its just normal rocker noise. and then i check down by the sparkplugs and i hear it but not as loud as by the lowerintake and head area. ill try and get a clip later today,,

    I have seen them for pedsital mount RR's on 5.0 as well as when you switch over to stud mount. Some off them look like they would really restrict the push rod from moving much of anywhere.
    I was thinking maybe they could keep the push rod from rubbing the head by limiting movement.
    I was not talking about using then in the capacity that they keep the rod from making the rocker possibly move out of position.
    Yeah, the piece at the fulcrum point of the pedistal rockers is rectangle vs round on stud mount, so they can not go any where.

    hmm, they end up doing the same thing, but what i did was legal. the pcv delete is illegal in smog states.
