In the interest of settling the questions about which and how many cams to lock, here are a couple excerpts from LN's IMS Solution installation manual:

"Lock right side (when facing flywheel) camshaft in place using IMS pro tool kit camshaft timing jig. Use the shorter cam lock on 5-chain and longer one on 3-chain engines."

[Note from LWG: The exhaust cam is not specified above, but an accompanying photo shows the bottom cam, the exhaust.]

"Some installers prefer to lock camshafts on BOTH banks of the engine. This is a practice that is not required, and is a matter of personal preference. With the crankshaft, and one bank of camshafts locked, all timing chains will be held tightly in the proper position for a successful IMS Retrofit procedure."
