The rear breather will have enough area - but it can sometimes get a fair amount of oil mist back there - make sure you're using a basket with the wire mesh. I normally use a breather in front of the intake or on a valve cover when possible - but sometimes cosmetics out weigh practicality.

We make some little drop in restrictors for Edelbrock heads that simply push into the oil feed holes - they have a .060 hole and seem to be plenty adequate. the intake gaskets are very good material, but you also need to have square and flat flanges for them to seal - I still tend to use a really thin smear of silicone around the ports just because...
