I have a 2004 gt that I just had the motor rebuilt in. We put in 10cc dished forged pistons and comp cams XE274H. Yes I know these are npi cams but they sound really good and my tuner said it would not be a problem. Question is I don't know if the guy that built it degreed the cams but the lift on them is only .500 instead of .550 would they still have PTV issues with the lower lift? I have started the car to check for leaks and it runs fine.

No you will be fine. If you do upgrade to the 550 lift, which I suggest you do, then you will have to get adjustable cam gears and retard it two degrees.

 

Cool I was just wondering about it.
