What is the stock length of small block chevy valves (exhaust in particular), and how is it measured when the valve had a dished end? Thanks.

4.910", and it's measured (as far as I know) as the total length as if the valve is sitting on the table standing up.

Somebody correct me if I'm wrong there, tho. It's either measured that way or from the actual seat surface to the stem tip...

Pretty close there KPLugnut,
Chevy used three different length's on exhaust valves:
4.90"
4.92"
4.93"

They are measured overall (tip-to-tip)
