Well I installed the spacer under my carb and pulled the valve cover and pulled the baffle that was too close to the valve cover.
I used the Moroso grommet that AndyF posted about and it works perfectly with the Summit plain Jane tall aluminum valve covers. I was surprised that my 493 is pulling about 13-15" of vacuum as I have never measured it before. I tried to follow the instructions when I set it up but I haven't driven it yet but my idle quality seems smoother. I'm probably going to have to jet up a little because of the spacer but we'll see after I put some miles on it.
So far I'm happy just to have a PCV on the car although I never had any oil mist around my breathers before and my engine is sealed up pretty tight.
