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?

Just FYI. Make sure the washer is on the side with the compression release lever. Some early engines had a washer on both sides until the folks on the assembly line were re-educated to only put a washer on the side with the compression release. The washer is only there to keep the compression release lever from rising up.

Before you take the top cover off again, (and I should have thought of this before), take the rocker cover off and remove the spark plug. Turn the engine over by hand and watch the valve movement. See if the valves are opening and closing when they're supposed to. Also see if the intake valve is getting bumped open on the compression stroke.
