Does anybody here have a factory spec for the 6mm valves used on the Magnum heads, specifically the OD tolerances, though any other specs would be useful also. I have bought a set of stainless valves and want to check them before the heads go in for rebuilding.

I have a Magnum-specific book coming, but I'd like to leave eBay feedback for the seller sooner.

TIA.

For the stems - and yes, 8mm not 6mm (not sure why I typed 6mm).

For anybody else who was looking for the info, it is:

7.899-7.925mm (0.311-0.312 in).

The eBay units are right on the money, the only difference is the face groove is somewhat smaller.
