Has anyone seen these cams from Kelfords?

276/272, with 12.5/12.0 lift...

234 and 230 lift @ 1mm

looks a little like the GSC S2 special cams that ER uses?

I have seen them before I think (or some high lift offerings from Kevin) but they push the lift higher than I would normally think works with the valvetrain geometry. The head would need setup to pretty exacting standards to make sure the rocker maintains contact at all points. Other than the lift, the actual cam specs arent very close to our stuff to be honest.
