Take your pick.. BSA cases are pretty good and do not easily leak... so what ever you use will likely do a nice job. FYI, the SRM guys use clear silicone adhesive, kind of like aquarium sealant... it is almost invisible should you get a small dab where you do not want it..
OK, here is a tip with the Pearson crank... you want to make sure the long bolts are in the "up" position when you put the cases all together.. The Pearson crank is a bit wider than stock, and the bottom of the long bolts will bind up on the crank if you are not careful.. and then those nice new long bolts will be slightly bent and want to bind after that.
I took some round aluminum and machined a groove..then use a zip tie to keep the spacers from falling off...
