What valves would you recommend?
I just purchase bare CNC ported 853 castings for my 347 forged short block. I have Comp 918 springs, Ti retainers, and an F10 112 LSA cam. I need to purchase valves, but have no idea what size or company to purchase from.
It's been recommended to me to use stock LS6 sodium filled valves, I haven't been able to locate any used. The other brand I've been looking at are Ferra.
Any suggestions or recommendations? Anyone have LS6 vavles for sale?

If you are running the lighter valves, it takes less spring pressure to control it...keeping the two halves the way they were intended to stay, in one piece. This of course assumes you are not going to spin crazy rpm's. There is alot to be said about upper rpm valve control. A heavier/larger valve combined with a heavier spring and retainer do not always make more power. The lighter valve with the light behive spring could possibly have much better control than the heavier single piece valves. Bouncing valves could not only damage a two piece valve, but beat up a heavier one piecer as well. Not to mention valve jobs. I say with the F10 go with the lighter valve, behive springs, titanium retainers, and rebuilt rockers.
