Folks at world,
For information only
I found a place near me that does nothing else but make valves - all
hardened correctly. I was quoted $48 for each of my Aston Martin valves,
they quoted $28 (For two sets it would have been $20) When they arrived my
75 year old ex-Aston engine builder said they were spot on (He mics
EVERYTHING) and pointed out they were in stainless steel.
