Default LT1 Stock Valve Size

Does anyone know the stock valve dimensions (meaning the valve head, stem length and stem diameter) for the LT1?

I know the stock stem diameter is 11/32. The LT1 intake is a 1.94 and the exhaust is a 1.50. Thats stock specs. Stem length is news to me.

I am looking on Summit, and they offer different stem lengths, so I figured they would ask.

Oh, do you mean the +.100 ones?

Those are if your valve seats have been cut down or other modifications have been made to your cylinder head.

nevermind, I crossed the PN from Thunder Racing in a Summit search and got exactly what I was looking for.

Thanks for allowing me to waste your time.
