Try a pan evacuator system, you can make your own with a smog pump check valve and a mopar style breather. There are kits available to do this. basically its what you mentioned in the head pipe or header collector you add a venturi with the check valve and run a hose to the crankcase vent. This creates a Vacuum in the crankcase, and expels any blowby out the exhaust. It will keep oil leaks in check, and at high RPM actually give you a couple of Horsepower. Drag racers have even gone to running smog pumps to suck the crankcase out, less pressure behind the pistons as they move = more horsepower, especially with a motor that has some blow by. A PCV system introduces this back into the combustion chamber, I'd rather it go into the exhaust, no need to contaminate the A/F mixture in the engine, and the exhaust is hot enough to burn off most of the blow by.
