Sorry i went off at a bit of a tangent, when talking about the other cam, the one in the motor was the one i was looking for info about. Andy, i don't think mine is the D6H because the guy at herberts said the D6H was .604/.604, whereas mine measures .585 int/.615 exh. .390/.410 lobe lift. I haven't run the car yet, the motor's been on an engine dyno but i've had .040 shaved off the heads since then, hence why the heads are still off the car.
