I've searched and couldn't find nothing. Does anybody know what the valve spring installed height is on an L92 cylinder head straight from GM?

Are you looking for the height pretty much from the base to the Retainer..I can measure it for you on my Heads, I have stock Valves.

Yes, that's what im looking for. I appreciate it.

I am installing L92 heads on my LS2 motor soon. I bought the heads bare & used all Manley valves & springs also retainers spring cups plus more. I plan on getting a new valve job before install & mill the heads .035 to come up with a 64 CC chamber. Not sure but I think I will need shorter push-rods??? Hope this will not effect intake fit?

I can't tell you right off hand but I would say the proper way to go about figuring that out is to buy a pushrod length checker and go from there. It'll be done right instead of guessing at it.

Yea, get a length checker.

Here..roughly 43mm from the Base to the Retainer when Valve is fully closed.
