Hey guys. I just put the "new" heads on the car, installed it, and then it fired right up. There is however a pretty loud tapping noise that it seems comes from the #4 cylinder. It's louder underneath the car, and goes away when rpm exceeds 2500. I checked the valve clearanced and they are dead-on. I also checked the tightness of the nuts securing the exhaust to the cylinder head. Everything seems to check out. I know my timing needs adjusting. Could I just be hearing a misfire? The car does this hot or cold.

The deck clearance checked out. There shouldn't be any interference with valves and pistons. The valves are also adjusted to spec. I have no idea...
Is there any way to double check the clearance with the engine in the car?
