Mine's been noisy too and that with a two times valve clearance check. I use the go, no-go method for checking/adjusting the valves. The car's always been noisy to me BUT it is especially noisy in the morning. By the time I get to work, it sounds only regular noisy. As long as you're confident about the adjustment don't worry much about it as long as the beast runs well. These are noisy machines that smell good.
