Dean, I don't trust any single can solutions that don't address both the crank and valve breathers. And any single can solution that does address both circuits is going to be expensive, 'cause it'll have to be big enough to allow the pressure differentials between the two circuits to equalize without pumping crank pressure into the heads.

You might want to look into the Crawford can. I don't think it will handle as much flow as the GST can does, but it's essentially the same device, plus it recirculates back to the intake instead of just vomiting air through a rag. But it's expensive like the GST can is.

Or you can go with a dual catch can setup, and even for relatively cheap if you go the Dean route and fabricate your own out of some 3" PCV pipe sections and caps. Hell, I've got a bin in my garage full of like 5 different catch can attempts if you want to sort through it for parts! We could probably do a dual setup on the car for the cost of some pizza at my place if you don't care how pretty it looks.
