Crankcase Evacuation System

I'm looking at buying an evac system made by Moroso for my 289. The style w/2 breathers running to the headers. I will be buying aftermarket valve covers.
Should the valve covers have baffles or not?

Has anyone used this system or something similar?

Where should I locate the breathers?

Approximately where should the nipple be located in the collector?

Any advice will be helpful.

I have a set on my dragster. I don't think it's that import when in the collector you put the tube. Just so long as you get the angel of the tube correct. The kit will have instructions. Mine are located at the start of the collectors, but I have seen them all the way at the end.

I have baffles in the valve covers. The breathers also have a baffle along with some foam and a screen to hold the foam in. Removing the screen and foam is a good idea on gas, mandantory on alky like mine.

Mine are mounted in the valve covers where the oil filler plug would normally go. But both are on the same end. Here are a couple of pics:


Since the pics were taken I swapped the v/c's side to side and put a longer hose on the breathers. The hose was too short and wanted to kink when it was at the rear of each v/c.
