List
OK, I'm going to hear a very BIG groan on this one! BUT here is what I did,
and it has worked for about 18 years or so. I have the CAT CLUB polished
valve covers and AFR165 heads with Crane roller rockers, and, as we all
know, there aren't any baffles and not much room. I made a small piece of
aluminum and poked a bunch of small holes (about the size of a small brad
nail) and cupped it so it would curve over the PVC hole (on the inside). It
would kind of look like a toilet roll cardboard that was cut in half length
wise, but not quite as long. This is where you're going to groan. I JB
welded the two sides to the valve cover; so, now you have a half of a tunnel
very close over the PVC hole (lengthwise with the valve cover). I then bent
the ends down a little so that the oil that is flying around inside doesn't
have an easy path to the PVC valve outlet. There is still enough openings
all around so the PVC valve breathes fine. This cured my oil consumption.
Here is where the biggest groan will come - the aluminum that I used was a
piece of a Coke can!
If you try this make sure the inside of the valve cover is SURGICALLY CLEAN
where the JB Weld goes!!!

The Edelbrock aluminum heads came with no rockers. The guys at Summit
selected
the rockers.
I don't think they are special other than able to survive 6,000 RPM, but
they
are physically bigger than
stock.
