[Fot] TR-4 Valve Spring Cap / Collar dilemma

[Tony Drews]

I'm going through my TR-4 head.  Since BFE seems to be out of action, 
I purchased aluminum valve spring collars / caps from Moss.  I find 
that they are smaller diameter than the cool titanium ones I'm 
running and smaller than my current springs.  Unfortunately, the 
Titanium ones are wearing and need to be replaced.  I don't have 
stock parts on hand to compare to, so I'm not sure if the Moss part 
is undersized or if I'm running larger than normal diameter stuff from Ken.

The valve spring collar I've removed is 1.365" diameter, the outer 
spring is 1.380" diameter and the alloy spring collar from Moss is 
1.260" diameter.

Anyone know of a source of lightweight valve spring collars for the 
1.380" springs?

TIA
