Fellas,
Who makes and where can I find a pair of valve cover spacers for Merlin heads on a Gen VI BBC? I have the "HP500" style aluminum GM's that interfere with the adjustable rocker lock nuts.

As always, thanks in advance!

CP Performmance sells them

I've got Merlin rectangular-port heads and the engines have the stock covers over Crane Gold roller rocker ams without spacers, and with the stock o-rings for gaskets. the drippers on the inside of the covers have been ground off but that's all. Don't ask me why they fit because I can't answer that. I bought the boat set up like this. Dave

Just grind the drippers of and the stock ones should fit

When you go to grind the drippers off I found it easier to grab them with a pair of vice grips and wiggle them. They will snap off almost perfectly. Then you can finish with the grinders. Your stock covers should work.

I've got a couple of sets of 1" spacers.

My builder replaced my Crower rocker arms with some Crane Gold and now the covers will not fit. Will the 1" spacers allow me to keep the original covers? Will they push the covers into the headers (Sterlings)? The builder has a set of the angeled covers (tall), but I don't like the look as much as what I had on there.

How much do you want for a set of 4?

you dont need spacers......loose the drippers and use the thicker felpro gaskets.

With my Merlin heads stock covers did not work. I ground the oil drips and even a thick gasket would not work. I went with tall valve covers.
