Older (pre-1985) smog pumps can be used, but that takes a little creativity. Another option is to install an evac kit, available from anyone who sells Moroso parts. It consists of two breathers with an exit on each, two one way valves, and two exit tubes. You weld the exit tubes into the exhaust near the collectors, and run a 5/8" hose from the breather exits to the exit tubes, with the one way valves in between. This set-up then uses the exhaust to pull the blowby out of the engine for you. It frees up quite a few horsepower, but if your blowby is severe, it can also suck oil into your pipes.
Take care,
