Just picked up a 1971 YS coded 400 for my 1971 Firebird Formula. This engine has oil deflectors above the rocker arms, should I keep them or remove them. Will be going with a slightly bigger cam. Thanks.

If you're keeping the same installed height of your valve springs and using stock stamped rockers there's no need to replace the covers with those that have no "drippers."

Thanks. May throw in a comp cams 268H camshaft and lifer set but nothing too radical right now.
