I am being told that 6mm stems now offer the greatest variety of possible valves for the 807/TS head.
NASCAR are a roundy-round race series using American V8 engines.
I think the intake valves are 2.02" but they may be larger.
They may also be Titanium if the rules allow.
I just tripped across Mecaparts offering new lifters with DLC face treatment, at "Only" around $500 USD. ::)
But this does encourage me to continue looking into practical lifter face treatments.

I have a source for DLC coating in California if you need someone to do it.

Banks has an aluminium oil pan that works well -- though I had to powder coat mine on the inside to stop some porous areas weeping oil.

Cam, Valves, Beehive Springs, are sending me in circles.
Each vendor wants specs from the others.
This is the cam I got back from the grinder.
Not sure I can use it, .470" lift at the valve?
The cam grinder says it is a Gordini spec.?
Cam grinder does not have any suggestions for Beehive springs, instead he suggest much stiffer springs than stock.
I need to find more of the original specifications as a starting point.
Some I can just measure, others I need references for.

Got my head back from the rebuild shop, HBR in Las Vegas.
