I went to mock up the stainless marine exhaust manifolds today and they hit the valve covers
I tried them with two different styles of covers

1 set was edelbrock elite series valve covers
the other set was a regular tall style cast aluminum covers which were shorter in height than the edelbrocks,
and the manifolds hit with either set

so guys that are using these exhaust manifolds what type of valve covers are you using ??

I have my stock set of covers still but they are not tall enough to clear the roller rockers
thanks

Merc 425 valve covers.

Merc Hp500's

Not sure what these are, they came with the old engines.

These are real nice and a great price... I'm running them with a Eddie marine long stainless risers exhaust system

i use imco valve covers.i have had them on two diffrent motors and i can remove the covers without removing the exhaust.i use a 1/4 " drive with flex-shaft extion,about10".the stainless marine were easyer to get to versus the emi,s,but doable.

when we did mine i used the stockers. just used two cork gaskets sealed together for clearence . works fine. mark

I have 2 sets of the same covers that Rookie has in post #2 for sale if your interested.

I also can remove my valve covers without removing my exhaust manifolds. I just use stainless 1/4-20 socket head cap screws and a 6"-8" ball end Allen wrench.

Eddie Marine for me. They are great with the socket cap screw. Nice valve covers!
