Thanks for the answers so far. Looks like what I need to do first is determine exactly which kit I need. I just skimmed through Pete Roper's 'definitive guide to rollerazation' on GrisoGhetto and I would guess I need a 'B' kit, but should remove a valve cover and possibly the tank before ordering. Money is tight for me, so I want to make sure I'm ordering the correct kit.
