I am far from an expert, but I'd wait for somebody who can verify it will fit under LS6 heads as well as LS1. Or try and find it through search. I don't know.
BUT what I do know is that the LS6 is listed as having a slightly smaller combustion chamber. 64.45 cc vs the LS1's 66.67 cc. Given that, it might be a tighter fit.

On zo6vette.com there was a guy who thought it would fit and ran it anyway on his zo6 with ls6 heads, few miles later he is rebulding the motor because valves were kissing the piston. FLYCUT! even if it clears, FLYCUT, that way you know it will clear and not be so tight.

With this cam, clearances are so close that it MUST be degreed upon install (you must get an adjustable timing gear set), and installed to spec. Lining it up dot-to-dot and calling it good is not acceptable. Gotta be careful.

There is a reason that people didn't think the G5X3 would fit on a 112. It used to be borderline common knowledge that the X3 wouldn't fit on a 112. Or so it seemed......
