There are original valves available on ebay.
Those are listed as "used". Mine are "Used" also. To adjust these the stem needs to be carefully ground and polished to meet the specifications. I prefer new or new subistutes for my situation.

One needs to be careful when purchasing "new" valves from ebay, or an unknown source.
The valve may have been ground for clearance, and when it was realized that too much of the stem was removed because the lifter was partially raised, the new valve was put back in the box before being lapped, and re-sold.
Of course, it will look like new, and it has never been used (run), so in the seller's mind it is still "new."

If you haven't found the valves, I'll check the 2 engines I have here with bad cranks. Might be able to pull a pair out and get you fixed up.

Thanks Kenny, I ordered the exhaust valves from ebay, they are Stens 505-044. The rest I ordered from partsandservice.com
not sure which engine I'll put them in yet. Probably the spare as it has the fewest hours after the initial rebuild.
