In the stickies at the top of this section, is a link to the disassembly of an Evo, you obviously will not have to completly disassemble the engine, but this will give you a good idea of what you are looking at for pulling it apart. I had to split the rocker boxes to get them off the heads and out of the frame of my '91 Heritage. You will need a 1/4 drive-1/4" 12 pts socket to remove the tappet blocks, a 3/8 drive will not give the clearance to remove. If you have a wobble extension you may pull it off, I do not have a set of those.
A manual is a great investment, along with the parts catalog. Just sayin'
