I'm building up my 2011 Silverado 6.2. Mods BW 80/92 1.25ar 15 plus boost Comp Cam 230/231 609/598 lift 115cl forged lower end 9.5.1cr with the ported 6.2 L9H heads. Question is the valves use stock valves?? Or get the LS3 intake and the LY6 inconel exhaust valve? Or what every??? What you guys think.

 

No one....

 

I think people might be confused about what your asking? are you asking to replace the l92's stock exhaust valve with with the exhaust valve from a stock ly6 motor head?

 

Stock valves should be fine

 

Was asking opinions on running stock valves or ls3 hollow stem intake and LY6 exhaust valve that is make from HD Inconel, Or whatever. I know the stock valves will work but this is a DD and tow truck plus track duty too. Thinking maybe the stock valves may not be the yes choice. What you think???

 

inconel valves for longevity and reliablity. the hollow stem ls3's can warp over time due to cylinder temps and pressures. not saying it will happen, just saying it can happen.

take note from gm. the ls9/lsa heads don't run hollow valves.

 

I dont think the hollow valves are worth the hassle for any builds personally. I buzz my stock L92 valves to 7500 fairly often. No issues so whats the need. Stock steel retainers 1518 beehives

 

I checked with GM Performance on the LSA intake valves. Sounds like the ones to go with. LSA intake and LY6 exhaust.

 

There ya go..
i use to tow alot and never hurt anything yet

 

I've heard of people recommending to use ls3 intake valves for boost.
