The BBK uses a .5mm base gasket for 7900 and a 1.5mm base gasket.  Unless the OEM 681 has radically different port timing numbers than the OEM 7900 timing numbers (since the BBK works on both) I wouldn't think timing would be a factor.  What I really want to know is there any difference in the cyls. other than price.
