When you get to the head you WILL have to replace the rockers and their pivot assemblies if you don't pull them out with a slide hammer first. I did the paint stripping first and when I put the motor back together the exhaust side rocker seized on me. I put plenty of oil on it but it wasn't enough, you'll need assembly lube. That is the reason I haven't got my quad up and running yet, I'll be pulling the motor back out and pulling the rocker arm out in a week or so. I'm currently building a slide hammer specifically for those little bastards. You're motor is looking pretty damn good, but you better apply some sort of urethane or epoxy coat if you want it to last. Remember that the more you keep polishing and buffing that your case will get thinner also. To get your cylinder polished up quicker use the red scotch brite pads, that'll greatly accelerate your progress.
