Because the 6.4 cam is bigger, I need to lock the VVT or the valves will hit the pistons?
I figure while the engine is on a stand I may as well make any upgrades while it's easy to get to.

New question.... I typically see 2 cams listed for a 2016 6.4 Hemi. I suspect one is standard and the other for automatic? Should I pick one over the other?

Thanks!
