pcv / breather / blower question

I am finishing up a 383 sbc with a holley/weiand 177 blower. I have a couple questions I am hoping to get some advice on. I am shopping for valve covers and prefer an old school finned look with no holes. After reading some of the advise on pcv's it seems that most agree it is the way to go. I was considering just using breathers on the side of the covers. When using a blower is it important to have a pcv? Could the pcv be mounted on the back side of the cover rather than the top. I was planning to use the old Cal Custom finned covers. Would I need a breather cap? I understand that with no cap, I would have to remove the cover to add oil. I feel the extra work would be worth the look.Just want to make sure and buy the right stuff.
Thanks in advance for any input.

You can make the finned covers work but it takes a little "cheating".

If you look in my pics, you'll see my 383 which is disguised as an older looking 327. To do this, I used an original Winters aluminum intake with the oil filler tube. In the back of the block near the distributor, there is a hole drilled and threaded for an elbow fitting. (You could achieve the same thing by drilling and tapping a hole in the back of the intake, but I didn't want to cobble a $250 intake.) From the elbow, I've got a vacuum hose running to the air cleaner. On the Corvette-style oil filler tube, I've got a pcv which is connected to the carb. Air is drawn from the air cleaner into the rear of the lifter valley. Air is drawn out via the filler tube.

It works.

Yes, you will need some sort of crank case venting. I run a PCV valve on my blon engine. I also used a breather tank. I am not sure how much boost you will be making but, you definetely need to vent that engine well. A vacuum pump could be used as well but, they will still require fittings in the valve cover/s.

I appreciate the input. Just won Cal Custom finned valve covers on Ebay.
So....I guess the plan is to run a pcv and try to hide it on the back of one of the valve covers. I may need to baffle it some how to prevent an oil problem.
I have the blower manifold so I can't use an oil fill tube. I plan to remove cover to put in oil, no big deal. Should I also run breathers on both? Or any further ideas?

Thanks for the help!!!
