The bolt sizes/quantities are all the same as far as I know. Can't think of a reason they would be different except the sandcast has 1 less on the clutch cover.
As of today 3/13/2012 my original owner 75 CB750F has made it through 3 wives, er EX-wives. Free at last.  ;-)

Be wary of the stainless steel crankcase (big) bolts: the ones I have seen with the socket heads (SHCS type) have smaller-than-JIS thread proportions and have damaged crankcase threads on 2 occasions for me. I use the stock crankcase bolts for the crank, then the SHCS on the others, with anti-seize on those threads.

I used alloy bolts on my engine and it was great. I followed the instructions that they provide. Anti seize and torque values given for each size. They also sent me two bolts which came incorrect. And made a custom set for me when I asked.

Are you talking your external removable covers  or the actual crankcase themselves.
