302 small block, i want to retain stock look.

which roller rockers can i install under my stock aluminium valve covers.

I do not mind doing some trimming on the underneath.

thanks

I run Comp Cams pro magnums under my stock Z/28 style covers, no issues. If they have the little cast in drippers they need to be ground out though, but not a big deal.
Do a search, I know this has been discussed and I'm sure there are plenty of other brands that work as well.
