Will these M/T valve covers clear adjustable roller rockers on ProComp heads?

I have the MT covers and I use sce 179076 gaskets. They are extra thick, it clears just fine. Depends on the poly locks you are using.

I have the Edelbrock version, same height and they just clear with 1.72 ratio rockers on iron heads. I am using the discontinued Felpro Permadry valve cover gaskets.

Just an fyi- Rocker ratio has nothing to do with it. As 70cutty said, if the poly locks are short enough you'll be fine.

True enough, I guess Scorpion uses the shorter poly locks.

Are these the small Poly-locks on my heads?

Those look similar to mine.

you will need double gaskets with those for sure. I use the edelbrock 1/4" thick ( they are a bit thinner than the 1/4' quote) and glue them to the cover with silicone and glue between the gaskets also and let set till dry. Do not put anything on the bottom and you can use them over and over again. If you have the a/c and alt brackets they will still clear them.

P.S. make sure you use anti seize on the plug threads and remove and install cold.
