If I'm read the IT rules correctly, I think you may be stuck using the cam timing that was available with the car as delivered (i.e. the workshop manual lists 3 sets: Mk1, MkII and later JH5 w/ emissions cams).
While other cam gears may be available, I think if you ever got called on it, the scrutineers would look at the published valve opening and closing time listed in the workshop manual.
Alternatively, I've never seen an 'official' JH workshop manual that ever listed the lift spec on the cam. Therefore, while everyone may 'think' the stock JH cam has a 0.340" lift, none of us in fact may be correct...
