Roller rockers stock valve cover

Is there a true roller rocker (not just the tip) arm for a 455 Olds that fits under the stock valve cover with maybe a thicker gasket? Thanks

s5016 for the best geometry

I use the Olds script valve covers with 3/8" spacers from Rocket Racing plus their thick rubber gaskets. Fits under stock A/C bracket.

^^^^^. Use a shorter stud and poly lock and they should fit under stock tins.

I have scorpion rockers, generic thin rubber gasket and factory valve covers. I think the poly locks touch the oil deflector just barely.

Hi,

Have 65 covers and had to remove the baffles to get them to clear, and thick gaskets, spacers might be a cleaner option?

Regards,
Jim

good point, forgot to mention that I used the provided studs, but got some 1" polylocks.

It's not the rocker that interferes, it's the tall adjusting nut. I cut four holes in the baffle of each valve cover so the adjusting nut pokes through.
