I think they're less aggressive than XER at some points, more aggressive at others. Not very familiar with how they work myself, but Thunder has had some success with them.

I have one and it's very agressive in its power production, but not in valve train harshness. Here's the deal: The TRak cam uses COMP LSK lobes for the intake and XE-R lobes for the exhaust. The reasoning is you want the most intake lift possible for best power and you want the quickest lobe from .006 to .050" on the exhaust to maintain torque production. The TRak cam delivers.
The LSK lobes are by no means slow. They're 1 degree slower from .006 to .050" lift than the XE-R lobes, but then they speed up and surpass the XE-Rs from .050" and on. The slightly softer ramp rates right off the seat will be kinder on valve seats, but the faster ramp rates after .050" and greater lift will generate more power.
Here's a comarison:
XE-R 232 lobe .595 lift
281 at .006", 232 at .050", 153 at .200"
LSK 231 lobe .643 lift
281 at .006", 231 at .050", 156 at .200"
Notice how at .200 lift, the LSK lobe has 156 degrees of duration compared to the XE-R lobe at 153 degrees. That means the valve will hang open longer and with a lot more lift. The TRak cam rocks!

) Don't think anyone's tried them with stock heads. They should work just fine as long as you have good springs like Comp 921 setup to the correct installed height.

Yeah, I think I read through every thread that had the word trak in it 
I think a couple people mentioned running this cam with stock heads but no real concrete information was found. Looks like I'm going with the tried and true G5X3.

We're working on a stock headed z06 at the moment with the lsk 239 at .050 intake lobe. It should be buttoned up this weekend if the cam arrives. Comp 921's shimmed around .050" from bind are the key according to those who've had success with these lobes, like Patrick and Thunder.

I think Patrick has done a few lapping events with no problems yet.

I just installed the TRak cam in my car with stock heads and it made 400 rwhp 371 rwtq and ran a 10.80 @127 mph on a 150shot this sunday.It use to make more hp with the tr230 412rhp 392rwt, but i think it just needs some tuning, and anyways the afr 205's and fast90/90 are on its way and should wake up the TRak cam.
