    The 270's have a radical idle and you need to change the valvesprings because the stocker wont hold up with the 270's. The stock PI cams and 270's are completely different. Go to videos.streetfire.net and search for Comp Cam 270 and listen to sound clips. Hope this helps you out

    Comp 262's would be my choice for NPI cylinder heads.
