Default LSX-DR valve lengths?

Trying to get a overall valve length to end up with a 2.100" ( or maybe even a 2.200" ) spring installed height to go on a new set of LSX-DR's. Anyone with experience with these yet? Thanks.

You are ahead of the pack, and a pioneer, good luck with your project, will like to find out the intake cc volume and the cfm flow per cc you can manage out of these heads, pls keep us posted...

LOL, not exactly a pioneer, our local GMPP dealer brought one by to see if we could figure a valve length for it. Seems he can't get any info out of GM. Anyone know of an adjustable valve length checker, kinda like a push rod checker? If we can figure out the details on the head we may get to do an engine using them, something around 440ci in an LSX block with the DR heads and a big turbo.
