Intake valves

I have an L76 I am building. Im having my heads ported and it got me thinking about the intake valves. What is everyone running for intake valves with larger lift cams? I don't like the idea of the stock ls3 hollow valves being they are a 3 piece design. I was looking at the manley stainless valves. Any inputs?

Aftermarket hollow stems... Have Manley hollow stems myself, setup for 700+ lift and 7500ish.

Correct.... definitely a better valve, just preference, budget and goal wanted. As long as you have enough spring to control everything, btw it'$ hollow. Wink,wink.....

Manley has the most valve choices for Lengths and diameter sizes. 6.3 length hollow stem valves available.
