LS6 valves question
So here's the deal. I'm bolting on a set of 243's with patroit dual gold springs, 7.400 push rods, and LG's G5x1"e" cam 228/232 with around little over .600+ lift. My question is will the stock sodium valves handle the pressure or should I just dish out more money and buy a one piece valve. All info and opinions PLEASE!

The stock sodium Z06 valves will handle these springs no problem. Don't waste your money on aftermarket valves.
If you go aftermarket you will have to dish some serious coin to get a valve that is anywhere near the weight of the stock valve and less weight is your friend when it comes to valves.

Sodium filled valves will handle the spring pressure. You could get by with a lighter spring and free up some power but its ok to run those if thats what you got. Those will definately keep the valve bounce under control.

Are you sure you have the sodium filled valves? Just because the heads are 243s, doesn't mean they were from a Z. If they are the Ti valves, I've never heard of anybody having problems adding the dual springs, and I've been reading the tech forums for many years.
