Not that it helps with your question much, but the GXP is like the new SS sedan, 415hp/torque LS3 so the heads could be different. With those different power ratings.

I used to have a G8 GT (L76) it had the gm 0821 casting heads which are the same as LS3 camaro's. I can't imagine the LS3 G8 GXP would have different heads.. that being said the heads on my L76 did have different valves they were solid not hollow or sodium filled

G8 GT heads should be L99/L92 heads or LS3 heads with L99/L92 valves and valve springs. These should be a direct replacement for a L99 automatic Trans 5th gen Camaro.

G8 GXP heads are LS3 heads. These should be a direct replacement on the manual Trans LS3 5th gen Camaro.

So long as your replacing the intake valves and valve spring kit the heads from either version G8 should work just fine.

Correct. Think of the L76 like an LS2 with L99 heads on it. GXP came with an LS3 both manual and auto.
I had a manual GXP.
