Going to upgrade to roller rockers this year on my 502...but need valve covers to clear them. What covers do the hp500 use? Do they just use spacers on the factory covers? I like the looks of the factory covers over aftermarket ones..

the roller rockers should fit under your valve covers.

I have the same valve covers. Wouldn't clear the roller rockers on my engine build. Got these http://www.diamondperformanceparts.c...3&cat=0&page=3

The stock covers WILL fit. You may have to remove the drippers - Roller rockers won't need them.

I removed the drippers on mine and still would not clear my Crane Golds. I guess it depends on the application.

my factory ones clear my crane golds with no issues...

Its a gen 6 502..yes the cam has been changed..it has the different timing set in it, and retro fit roller rockers.

I have already ground down the rockers..
