pcv and thermostats for street strip cars ?

Something I havent seen talked about much. What is everyone running for a crank case vent on there street strip engines. My motor is a little nastier then most street motors, lots of over lap and duration and 11:1 compression. I really dont want a PCV valve contaminating the in coming air/fuel mixture. A pan Evac set up wont work well with my mufflers. Will a couple of breathers be enough ? Are there low buck vacume pumps that will live on a street strip car ?

What about thermostats ? 160, 180 ? I have a radiator and shroud from a 340 car and will use a clutch fan. I really dont want to test the rpm limits of the flex fan I have. I would like to go with a Moroso electric water pump and a electric fan at some point. The moroso pump doesnt use the by-pass hose. Can you use the thermostat with out the by-pass hose ?
