The cast aluminum corvette valve covers were made to fit both the staggered 
bolt hole pattern on the early V8's and the straight bolt pattern of the 
later V8's.  Many of the Corvette mail order parts (Ecklers, Mid America, 
etc) offer both types of these covers as reproductions and they're no more 
expensive than what you would pay for Edelbrock, etc.. . .in the $50-$100 per 
pair range.  I'm interested in doing this as well eventually but have the 
same concerns and don't want to cut on the covers.

The assembly manual shows an optional early pcv setup that pulls off of the 
oil filler tube and into the carb base.  Would this be sufficient?

<<Hi Bob,

I had a set of valve covers like that one time, and when I tried to put
them on my truck the bolt holes wouldn't line up.  It's possible I have
350 heads on my motor; last time I had the valve covers (cheap chrome,
now) I didn't know about casting numbers.  But that's something you
would want to make sure of before you start modifying the Corvette
covers.  

What year is your engine?  Mine is designed to breath through the oil
filler tube cap and a down draft tube at the back of the engine; for now
I don't have any breathing through the valve covers.  Would that be a
good thing for me to install?  Since my covers do have the holes for a
breather, I just have plugs in them.

"I have an old set of Corvette aluminum valve covers that I would like

my small block. However, the Corvette covers don't have any holes for
the pvc
valve or a breather. I was thinking of adding some holes somewhere in
the covers
to allow for a pcv valveon one side and a breather/oil filler area on
the other
one. Anyone have any advice on doing this? I assume if I do I will need
some
baffle on the inside to keep the oil from spashing out the hole. Anyone
else
ever done this?

I was faced with a similar situation with a set of old Edelbrock valve
covers.  There really is only two solutions.  If the block is old enough
to
have a draft tube, use it w/a pcv valve and let the oil filler tube
breather
cap (if the intake manifold has one) be the source of outside air."

Robert, how do you use a pcv valve with the draft tube, and what would
it do?
