Make sure you purchase a good Torx T 30 socket to remove your cam bolts. I broke my Proto when I initially tried to remove them. Took a hammer and large punch and shocked the bolt heads to help free them up. They loosened off easily after that. I adjusted mine at the 14,700 km mark and had to replace all the exhaust and 1 intake shims. They were all loose. Had to go through the process of measuring the clearances, pulling the cams, measure the shims, reassemble them, order shims and then repeat the process. It went off without a hitch.
Save yourself a few bucks and try it yourself. The hardest part is starting the project.
