    roller rockers under stock covers


    Hi guys,

    am really enjoying this forum, have been reading back and am only on page 7!! There's a lot of expertise out there.

    One question I've wondered about for a long time: is it possible to fit roller rockers under the stock tin covers? If not, which bit hits - rocker itself, or poly-lock? I'd quite like to fit CC Pro-Magnums, but I need to keep the motor looking stock.
    At the moment I have plain Magnums with roller tip, and am running mid-.500" lift. Springs are CCA 26120 beehives rated at 130lb/in. Would I just be wasting my money??

    The locks stick up the highest,if you can set a stock cover in place without a gasket,you've got plenty of room,if not,measure the interferance, maybe you can get by with a premium cork gasket,they are a lot thicker. I had roller tips on mine with no interferance. Hank

    You can also double the gaskets (glue/seal thoroughly together) and I've seen billet Al spacers in Summit or Jegs.

    The cast aluminum covers for my 502 had to be milled out 25 mils on the inside along with double gaskets to clear the nuts on the roller rockers. And then of course I decided to not use them anyhow
