Just remember Silicone doesnt like petrol , so I would stick with the Three Bond , its designed for 2 stroke crankcases where leaks = no power ,
I've allways used a thin smear of gasket cement on gaskets, and Red Hermetite for anything petrol related.

Just taken apart my Suzi GT250 crankcases which the previous builder had used blue silicone on hed also rebuilt it with a rough main bearing , now that was really going to work !

If your building it and leaving it for a few months try using Graphogen on the cylinders and other surfaces that might rust.

 I like to use Blue Hylomar on base gaskets around the oil ways, making sure that there are new 'O' rings around the cylinder sleeves where they protrude down into the top of the top crankcase.
The 'pucks' under the cam carriers is another good place to use Blue Hylomar.
On the OEM 750F2 head gasket there is a coating around the cam chain tunnel which should melt & seal this area, but if as Peter says there are a few 'imperfections' in the gasket mating surfaces I always use what Pops Yoshimura recommended, which was/is a thin smear of copaslip on the head gasket. Since learning of this trick i've done this on all graphite head gaskets, be they car or bike, & never had another gasket let go.
