[Roadsters] Valve Cover discovery...

[Eddie]

Interesting, thanks for the info.

What seems odd is that my cover, in the spot where the breather tube 
goes, has a round circle there.  Like it was designed to be "drilled" 
out or something, but never was.

Well, I guess I've got a 1500 valve cover in my box of toys!
