nothing, heads are the same. difference was pistons/compression on the two.

both lower compression about a point so thats a definitely plus...and the chambers/valves are as big as the LS6 heads ...so its the best of both worlds...
the 6.0 heads pple like for boost have a 317 casting on them...good luck. nice mods
