The 750J had 1100 spec duration cams and the 750k had the same inlet cam but slightly less aggressive exhaust cam. Fitting 1100 cams will net you the same result. The smaller volume dot head bumps up compression, whilst having pretty much the same size valves as 1100/1157(exhaust the same and inlet a gnats,0.2mm smaller) - which as FBOB says works well on the lower compression B12 - you could drop 1100 cams in your motor, but the compression would need to be bumped up to get better response (still get more top end).
Tried to use my old 'OilySpanner' on this new site, but I made a right balls up ! couldn't see what I'd typed in - so Oilyspannerlyspanner it is .
