Like snowrules said...dry fit the cases, set the circlips/thrust rings on crank with no seals and give it a spin...install all the bolts & torque to specs...give it a spin...all should spin freely...once you're happy with it. Split it again, inspect it, clean it up if you have to, and then you're ready for reassemble...I placed my yamibond on the lower case only,(w/crank in place) tight to all the bearing races & bolts holes, dowels...for the seal I just used red locktite (Brushed on the outer side, I used this cause I did not want the seal to leak air or spin on initial start up) Remember to put grease on the seal before you slide it on the crank & set in. I lube the water pump/oilpump cavity and oiled the crank really well before my final assembly...Try & put all you bolts in & snug them up (TIP: paint you're bolts with graphite spray, helps towards corrosion), I only rotated my block quarter turn to access for torquing (remember to rotate the crank at each bolt torqued). Also use yamibond on the water pump cover...All you need on the base & head gaskets is gasket spray, a light coat on each side is all you need...same for the reed blocks...on the exhaust side I used the hi heat gasket maker stuff & on the donuts...hope this helps out...cheers
