Crankcase Ventilation for Blown Engine

I have a 350 chevy with the smaller 142 Weiand blower. The engine has been rebuilt with forged pistons, crank, etc. appropriate for a blown engine. Before I rebuilt the engine, I used to go through rear main seals more often than usual and told that the blower may be creating too much crankcase pressure. The rebuilt engine will be show quality, with many billet parts. My question is what is the best and most attractive way of relieving this pressure? Will adding additional valve cover breathers do the job, or should I consider something else? Any advice would be appreciated.
