My 'shift kit' is a full workover by Libery Gears and a RAM 10.5" dual disc clutch I like my hotrods with 3 pedals.



The Edelbrock Marine heads come with a black anodized coating and the only difference in valves are the addition of Inconel exhaust valves, and no valve springs/retainers come on the heads from edelbrock. Other than that they are exactly the same as the Performer RPM/GM ZZ big block heads as far as I know. Of course I could be wrong. I had already made the decision to get the head fixed for use in another project and I'll be replacing all the valves at that time. I had the heads checked out and put on a flowbench before I ran them on the 454, but obviously that didn't matter.

Maybe.. I'd have to call them.
but I'd hope a car set would have 1 piece intake valves.. if not all, the ones for roller cams.
Marine use a 2 piece valve would be no issue.. as it be lumbering along at 3000-4500 rpm.. set rpm.. or less..
Did you check the spring pressure after tear down . seat and open to see if at it's installed height( in head as used)it was within spec for that cam??
I.E. did it float the valve.
