Default What the diff between LS6 and LS2 heads

What the diff between LS6 and LS2 heads? Do they flow the same and are they interchangable? This is why i'm in the newbe section.

Both are 243 casting, yes they are the same. I may be wrong about this, but I think the ls6 uses sodium filled valves , and the ls2 doesn't...

Are the 243s the best stock head in the LS line? LS7 excluded.

there is no BEST. Its what is bes tfor your application. The truck heads because of lower compression are great for f.i. but not for a n/a application..ect.
