I did my 85 EVO with 82k this summer. I couldn't get the case studs out after some effort so I left them in. The threads looked good. The Head bolt/screws did show some wear. I sprayed some cleaner up into them and a fair amount of metal came out. They didn't cost that much. The only thing I had problems with was keeping the middle Rocker covers from sliding when torqueing down. I will probably remove them later this winter and try installing some pins between the middle and top rockers. I think Drag Specialties has some 1 piece Rocker covers too. I bought a special flat wrench from Motion Pro with a alllen welded onto the end for $15 which makes torqueing down the Rocker bolts easier. Good luck with it 0 Bob
