Alright, i'm in the middle of this damn PI swap with my 98 GT. Turns out my piston to valve clearance is way too close for comfort. I really want a choppy idle so i have no idea what cams to get that will fit. People are telling me to go with comp cams XE262AH to work with my car. But the duration is really small so the idle we'll be way to smooth, plus they are only rated for like 5,400 rpm. Anyone been in this situation that can help me out?

Go with a VT stage II. You're still going to have to degree them to be sure the events are where they're supposed to be. But you shouldn't have any issues with those cams.
However, if you're seeing issues with stock PI cams already, you have something not quite right. Maybe a tooth off or something.

You asked for help. Now you don't want it?? Why would you elect to leave power on the table?? By degreeing them, you're assured of getting the most out of the cams you just spent $600 on. It takes maybe 1/2 hour to do this. If you don't degree them, you could be robbing yourself of 10 hp.
Oh, and if you're using Comp cams, you'd better degree them!
I reserve the right to say "I told you so!". BTW, you degree the cams, not the pistons.

I don't know who you talked to, or what information you gave them, but unless you're running 278's, you can degree them so as to not have a problem with PTV contact, thus you would not have to remove any material from the piston. BTW, just for everyone's sake, you mean .5 mm, not .5". 
I have VT Stage II's with no issues.

oh really
well now, guess I'll also have wait for the BIG KaaBoooom
oh really
well now, guess I'll also have wait for the BIG KaaBoooomDegreeing cams for mod motors are very new, within the last 6 months, so what were people doing before than??? It is better to Degree the cam, but it only adds a few extra hp and for the money and the time to do it its not necessary. These are my second set of cams, i had a non PI cam in the car for about a year and it wasn't degreed than, never had any problems with it.

wrong again, modular camshafts have been being degreed for years. I had my Crane regrinds degreed way back in 2000 on my Gt, of course I have adj cam gears that made the job eaiser

I once went down to a local shop to witness a big boom, this guy building a nice 347... Some really nice brand new expensive parts found a new home in the dumpster out back that night.
ANTIRICE98.. I strongly suggest you do some reading on installing cams before you try to tackle this. I am not trying to be a jerk, I just don't want to see you trash your motor.
I'm not doing the installation, I know i don't have the knowledge to tackle this. I'm having a friend who has built multiple mod engines for many years build my motor. Like I said he didn't degree his cams in his built motor and he's been running the **** out of it for 2 years straight revving up to 7k rpm and dropping the clutch at 6k rpm at the track. He's had no problems what so ever.
