looking for info on pi heads and blowers

Your compression is too high to do a blower properly, unless you changed out your pistons while doing the PI headswap - tough to tell when you haven't given us alot of info on your ride.

On that note tho, nitrous loves higher internal compression numbers...
 
Well, seeing as how you're hovering in the 10.4:1 range, you're gonna have to keep boost levels low and pull a lot of timing in order for it to work and stay together. You'll still make great power though. As Miles stated, nitrous is another great option....especially with a higher compression set up like yours.
 
Also, It depends on what gaskets you use. I think if you use a thinner gasket it lowers the compression retio a little. If you do put a supercharger on you will want to run low boost due to your stock pistons. I would seriously look into the nitrous.....either NX or the original NOS brand.
