496 valve covers
 

Hi guys, nice forum you have here. I dont own a boat at the moment, but I do have a silverado with the 8.1 engine.

I have looked high and low for a set of "tall" valve covers to fit these new style heads. The classic BBC valve covers just dont quite line up with the holes.
I need something taller than stock so I can run a standard adjustable valvetrain with roller rockers and 7/16 studs.

So my question: Who makes valve covers for the 8.1L heads? Or what about valve cover spacers?

Thanks for all replies in advance

John
