I ordered the cometic c7070 top end gasket set. It says its a 72mm according to the cometic website. Its all they sell I think for the 85/86.  Will this be a problem? I got All Ballz crank bearings and a complete cometic gasket kit c7070 and c3363. I also got 3 different types of crank seal seals. I got cometic, all ballz, and s&k.  Which ones would you use?
