Default Civic RPM problems

Ok, here's the story, kind of long so bare with me and I'll appreciate any help I can get. I have a 95 civic with a d16z6, i just had the head rebuilt with new valves put in it. I was told one of the valves may need to be adjusted, but other than that everything was fine. A while back, my timing belt slipped off and luckily the only thing that happened was that 2 exhaust valves were bent in one cylinder. After a new belt was put on the car started fine, but idled a little weird and the redline was different. Since I've got it back from having the valves replaced the idle is a little more normal but still not the way it was and the redline is still off. The redline is at about 5100 rpms, where the stock redline is 7200 i think, and the revlimiter is kicking in well before it normally did, like 5800ish. Would the valve that may need to be adjusted be causing this? Are there any other things/problems that would cause this to happen? I'm thinkingthe timing may be off a tooth or there's an ecu problem, but I would like to know any opinions first. Thanks for reading!

it sounds like the timing is off by a tooth, and do you have any trouble lights on? i know if your oil level gets too low, the ecu can cut your redline down.
