yes Doug, prestone is the antifreeze of choice and temp is important to keep from discoloring the aluminum(wow i think i spelled it right)
disassembly dificulty depends on your expeirence, i will give you a link to bill robisons post on how to below.
it is a post on how to replace bearings. if you need to do more let me know, i just did my cam, lifters,push rods, valve springs and bearings and it all worked out fine, just fired her up and man did she purr

i used a two arm puller and just put the grabbers in the groove that is right in the middle of the hub.
bake the case at 250 for 20 minuits and use a wooden dowl with a HAMMER to knock them out and have the new bearings ready to go in and you only have to heat it once, just put the front in first and then put the rear on the crank and then put it in(that way the front keeps the rear in line) and use the wooden dowl to tap it in. see the puller in the pic below Ron.

go with this set and order double seal on the front,(no seal on the rear)
