[Fot] TR4 Valves

[Joe Boruch]

As a result of my broken timing chain, all but one of the valves are bent.  Since I still race SCCA, I need stock diameter (head diameter) valves.  The stock diameter valves do not have the stems necked down for better flow.  When i built this head years ago I bought the oversized valves with necked down stems and ground them down to stock diameter.  
My question for this esteemed group is - Does someone make or sell stock diameter valves with 5/15 inch stems that are necked down for better flow?  I was thinking I might need to have Manley make a custom set? JoeB
