Slant 6 904 parts for v8 904 ?

Hi guys i have a very nice 1986 s6 904 and a v8 904 with a 2000/ 2 200 stall, do all internal parts of the s6 904 fits the v8 904 ? Its to bolt on a 350 hp 360 engine....read that the s6 904 as a better 1st gear ration than the v8 one....thanks guys kinda new to 904s , can just buy a 727 but i have these 2 laying around.
