Just a little update. I haven't really driven the car lately and decided to take it for a drive. Noise is still there. Just out of paranoia I drained some oil and checked the plug for metal. All seems good. Like Don said could it be the valve springs being worn? My first motor didn't seem to make this noise. I am using the same length push rods. 7.4 valve springs are patriot dual golds.
