The only thing during installation is I had to drill a hole for the mounting plate, see the far right mounting bolt in the picture I provided in the earlier post, where the support plate kicks out. It doesn't go into a water jacket or anything, but I used a dab of silicone on the threads to be safe.
The cam gear and hub assembly have adjustable bolt patterns, so cam timing isn't an issue. One tricky thing I do remember is during and after installation, the instructions state to run a piece of newspaper between the gears to get the proper mesh affect, if you will...
