Now that I got it tore down...I was thinking, could I use 6.0L lsx valves? 2" intake 1.55" exhaust. I'm assuming they're both 8mm stems, not sure on the length but I could pick up the valves cheap from a local pickn'save...and thoughts or info on the subject?

I've heard they don't respond great to porting, I know GM did the same thing with the old vortec 350 heads...very good design out of the box...if they flow another 20 cfm, it would be worth it. Probably 30ish horsepower. I'll look around for that threadOriginally posted by bigcheese View PostSomeone else put larger valves in and it didnt gain too much flow from what I remember. 20 com? Maybe? There was a thread on itLast edited by trash boat; 10-29-2017, 10:06 PM.
