Some questions about pcv vacuum hook ups on my FE390 with a race cam
Hello again. Recently I had brought up a situation where there was too much oil build up in my valve cover on my driver's side of my FE390. It does have solid lifters, heavy duty springs and a race cam in it however I did not install it myself so I don't have the specs. The guy who originally built it mentioned something about a 5 point cam or a .5 something. Sorry but he was really strange and had the car practically stole from him so he was quite bitter when talking about it. . My question about this set up is that the Edelbrock Performer carb and intake when put together partially block the front vacuum passage where I have the pcv valve hose connected. There is a split down the middle of the intake port so it is goes right over the vacuum port on the carb. There is some passage slots that go to both primary openings so there is still some vacuum created. I was wondering if I should connect the pcv hose to the vacuum port on the back right of the intake where I have my transmission and hook that line to the front of the carb. The old Weiand intake that was on this car had about half of the center separator part cut away from it but the cut looked factory. It was also on the back half of the carb. This car has a high volume oil pump in it and combined with the race cam and lower vacuum I was thinking anything that I can do to draw more fumes and pressure out of a newly rebuilt engine like this would be beneficial. Any thoughts would be greatly appreciated.

I'm getting 13 psi vacuum at the pcv hose while the engine is warmed up and idling at 1000 rpm. Is there a certain rated pcv valve I should ask for with this amount of vacuum?
