327 Not Breathing Right?!?!

I have purchased the baffled grommets that can be installed on the rear of the valve cover, but that is a last resort. Although it seems that it would be easier and more effective than drilling into the intake at this point. This is what I purchased.

these are exactly what i was looking at in JEGS to use on mine, and just put them at the very back , run one of the square breathers turned sideways ?? just what i was thinking of doing

When you drill into the back of the v/c's make sure these don't stick to far in and hit the rocker arms or lifters. I had to make mine shorter than I wanted to because of this issue. When I made my tubes (for the v/c's) I built two baffler in each to try and keep the oil from slinging up into the tube but still allow air movement. I also built a "catch can" type box to house the pcv and the breather. In theory my motor should pull in air from the old oil filler tube (it's been modified) and from the breather and the pcv "should" pull the fumes....should. I've only had it running for a little while and I'm still working the bugs out (other issuse not related) so I will report back after I get some miles under her. Here's some pics of what I did....
