If the camshaft timing mark is aligned correctly, and the flywheel key is not partially or completely sheared, then the timing on engine is spot on.

What's going with it that makes you think it's out of time?

hard turning over like the valves needing adjustment

I suspect there is a ACR issue not releasing compression to crank the engine. Have replaced the ACR on the camshaft a couple times, but ends up being a temporary fix. Have also had to replace the cam gear in conjunctio with the ACR but even that can still result in intermittent issues.

There is an intake timing mark and an exhaust timing mark on each cam gear. Could you have possibly lined up the marks on the wrong sides?
