Need source to buy 1 replacement flathead valve

I need to replace 1 valve that has a bad face. I'm pretty sure its already an aftermarket valve it has MEP V967 marked on the stem. Its stock size 1.51 head 4.820 overall length and 45* seat face. It has rotator retainers if that makes a difference, hoping to find same brand to replace it with if possible. Looking for a good source to buy from. Any Ideas?
Thanks in advance Mike

 

Try http://www.sivalves.com/ they may have what you need.

 

I was able to track down the part number on the stem its a Federal Mogul number and the Valves can actually be ordered through O'Reilly's

 

Did you try EGGE MACHINE COMPANY?
