Valve to piston clearance

Yes, I remember you saying that.
I'm just stating the relief depth is listed, but not the valve size they were made for.
I love a good mystery... in the theater, not while building an engine :)
They list the angle of the reliefs.. pretty important, as long as the TF-270's valves are on 15°, you're good there...
(wish you were a bit closer...)
