Just as the title, how do you know a sodium filled set from standard valves? I have searched but not came up with any results.

measure the overall length, thats the only way i know of, the hollow stem valves should be .6mm shorter than standard valves, because the ls6 went through some valvetrain changes in 02 and that was one of them
You have this backwards - the LS6 valves are longer.Quote:

Weigh them
The length of the valve will not tell you much other than whether the valves were used with a higher lift cam (ala LS6)...as sleeper has said, the true test is weight. I forget the actual numbers but I beleive that the standard valves weigh around 90 grams and the filled/hollow weigh closer to 60.
