WELCOME TO TEAM NOVA!!!Will not clear roller rockers, you have to get the taller vc..you can get a smaller booster!! What size booster is on there now?? Stock??

Kevin they will not clear roller rockers unless you grind down the oil drippers that are cast inside the cover; then they will clear the lock nuts used with all brands roller rockers except for those used with a stud girdle. They will clear all accessories except the power brake booster in a Corvette C3, C4 models.

Big davei have these vc's and they will not clear roller rockers even after doing what dave say's!!.dave, in case im mislead, tell me what roller rockers will clear the covers..thank you..

It is the rocker poly-lock nut that hits (nut that holds it to the stud). I run the blue Moroso thick valve cover gaskets (it has a steel core and steel inserts that prevent over torquing the gasket to control leaks). I used Crane Gold rockers with this combination on my ZZ502 that came with these O-ring seal covers after using my Dremel cut off saw to flatten all protuberances under the cover. Because the rollers have wide bodies they also hit the internal baffles for the oil separator under the cover and I had to squeeze the baffle plates with channel locks to get it to fit (broke one off one so it went on the air inlet side).

Big Daveah hah!!..ok!! thanks for the info!!

I am going to use the crower stainless rockers .they have a much smaller body than the aluminum rockers. I am also useing the thick steel cored rubber gaskets

I had to use tall valve covers on my 327 with crowler roller rockers
then I had to deal with all the brackets to run p/s, factory a/c,
and altenator...made it work and belts line up good
