PI headswap w/ Nitrous vs Blower

PI headswap w/ Nitrous vs w/ Blower

I am getting the PI headswap done sometime in January, I'm looking to make the car an 11 second street car. My question is should I go with a blower or nitrous after the PI headswap. I know you can grind out the swirl dams with the PI heads so the compression stays the same which would allow me to get a blower. My only concern with getting a blower is my car has 74K miles on it how long will the bottom end last on a blower with a car with that much mileage? With the nitrous I would leave the PI heads as they are because the nitrous loves the compression. I've heard that the nitrous is just about as hard on the engine as the blower is if you dont drive like a maniac with the blower on there any truth to that? I would rather go with a blower than nitrous but am really just looking for the option that is going to put the least amount of wear on my engine.
 
if you remove the swirl dams AND get cometic head gaskets it should drop your comrpession fairly well. but since you want to drop into the 11's with a power adder you should get forged interals to make that power safe.
