Default hollow stem valves in 853 casting heads?
Can i put the valves out of a set of ls6 heads into a set of 853's? I heard that hollow stem valves are longer.

You have heard right the LS6 valves only fit 243/ 799 heads they don't even fit well enough to run on a 241 head.

Do all 243 heads use a longer valve? If so, what length are they? I have a set with standard stem valves.
