HP500 valve covers
Can I use late model HP500 valve covers on my Merlin heads with .630 lift cam. I was about to buy a pair but the owner didn't thinkthey would fit.

My boat has the Merlin rectangular-port heads and Crane Gold rockers with the HP500 covers. They have had the oil deflectors ground off on the inside but still use the stock o-ring gasket. I believe my cam is slightly short of .600 lift though. Mock it up and you'll be able to see what it's going to require for gaskets.

You'll need to grind a little off the corners of some of the rockers (if you're using Crane Golds).
I've got a few sets of 1" spacers for valve covers lying around.

Yeah, mine has one rocker on each side that's had a corner dressed on a grinding wheel. But I've seen this on all the engines equipped with these covers as well as the older Cyclone/Weiand covers.
