Got the Pi Heads and intake now i need help with a cam

Hey guys So i picked up pi heads and an intake off an 04 For My 96 Gt. My delema is a cam. i wanted to go with comp cams but was told "your pistons need to be fly cut if not they will hit stock piston so look into those things before install". The car is driven about 5 months a year during the summer . I am looking for a streetable cam i want performance and drivability. I was looking at comp cams Stage II Xtreme Energy XE270AH Camshafts . is this true for the fly cut?
i was gonna replace the springs with COMP Cams 26113-16 - Valve Springs
Im new to this and you guys have really helped me out before with my suspension and why I went with the pi swap
Am i on the right track ?
