Alright im writing this for a buddy who has a 98 GT and wants to run those cams. My question is will those cams be too much for the stock NPI heads meaning the lift and all that. I told him he should do a PI swap on the heads anyways but he doesnt want to do that till later.

so what do you guys think would it be to much or no?
