Since the cams are very new there isn't any info on them as yet. Am curious as to anyone with experience with them. Are they safe on the stock ITR valvetrain to about stock revlimit say 8600. I ask because I have Spec-A originals and would like to try these out. The originals are good to about 9k with stock valvetrain although not much power up there wonder if the A2's would be ok to 85-8600. If I remember correctly toda even use to say the B's where ok with ITR but later changed it. Any opinions and better any experiences with the new cams yet.
