    Mystery Valves.

    I'm just looking for someone to confirm these part numbers for me

    These are 2 piece valves like stockers, but +1mm. Not back cut. Nothing very fancy.

    P4876670 - G head big exhaust valves, needs oversize seat.
    These appear to be made in Argentina, or at least the ones I have are. 1 square tip groove, not multi-groove. Stainless, tulip, swirl polished. Appear to be pretty nice valve.

    I can confirm these, but not top two #'s.

    Re: Mystery Valves.

    I have a set of +1 G head valves, I'll have to dig them out to confirm but I think the EX valves are multi groove so they made them both ways then. Their new in the plastic but it's little cellophane bags so I don't think I have part numbers for them.

    So will I need new keepers to run the exhaust valves? My spring compressor broke last time I used it so I planned on having the machine shop install everything after cutting the seats.
