Hate to be the bearer of bad news but you most likely wiped a lobe or two. I did it last year with one of these cams and it ran fine but was very noisy. I adjusted the valvetrain a few times to no avail. When it started idling weird I knew what it was. 2 wiped lobes. Oil pressure doesn't really tell you jack in most cases. I hope for your sake I'm wrong. J.Rob
