I have a 98 gt and want to get pi heads, but i have a super charger. I hear the compression ration will rise with the pi heads and that will make the engine go boom. if i don't go with the pi swap will it hurt me to get the Non pi heads port and polished and throw in a blower cam?

I would say either P&P the heads, or order these heads from SHM. I heard removing the swirl dams on the PI heads lowers the compression but I would still be hesitant. Either way, good luck.
what you can also consider is getting Cometic head gaskets and swirl dams removed, they help lower compression.
Also using a intercooler helps with retard.
herd that you can salfy run about 6psi withe the new heads but maybe u would loos power if you decreased your boost from what evcer it is at now. youd have to do the math one that one
