VG34ER cam gear synchronizing (VG30 & VG33)

It's not uncommon for the lobe centers of cams to be off by a degree or two and this can cost a few HP. Here's how to check and correct the error on VG series engines. This technique can be used on other OHC engines but degree of separation may vary.
This video does not take into account degree from Cam to crank, left cam was already exactly where it needed to be so I decided to retard the right cam to match.
