There a plastic bushings that hold the cams into place, mine were so tight that it wasnt allowing the brakes to return so they were always so force being applied to the brakes. I bought shoulder bearing (2) and fixed that issue. You could also just reem them out just a bit so they have plenty of room to twist.
On the diffs, all shims to the gear side, 4 might be a bit much, Ive got 3. Headed to Indiana for the pro series event, hope to qualify better than 15th and no rain so we can run mains. Im running 7-10-1 in diffs, 700 front shocks and 800 rear. Pro-line hole shot tires, that is untill the AKA stuff come out in a few weeks.

Nascar i took the diff mount to peices, the cam holders move liek they should, im going to put tiny springs between the brake pads like the buggy has, so they wont be lose and free. Just need to find where i can get springs that small from. Theres a chance that some flanged bearings i had laying around somewhere would fit, hope i didnt throw them away. I put 2 shims on the gear side and its a nice snug fit. Going to order some bowties with half offset before I go down to the track this weekend, then i want to get some AKA tires soon after they come out. Any chance you can get a pic of the truggy or buggy aka's?

For the diffs, I ran 10-20-2 and wasnt thrilled, went to 7-10-1 and like it alot better, just feels and reacts better for my driving style.

Thanks!

Like hkenvy said, blue if your going to use any. I myself dont use any on the engine screws/bolts. On the cooling head, If you take it off (sirio to change to the turbo head) then after you run the first tank, check them in a cross pattern. I always check mine from time to time as with all screws and bolts.
If your going to use blue, just a dap will do, dont coat the threads, bad things can happen.
