Ok... So I have been working on the motor all evening. The preload is actually about 40 and my rockers are hitting straight on the valve and no contact with the keepers. After checking everything I could think of I decided to run it a bit wight he valve covers off. I noticed no significant noise coming from the driver side. It seemed to be coning from the passenger side toward the back. I tried a banner handle on the rocker and noticed an ever so slight change on the second to the rear rocker. When I shut the motor off that particular rocker was all the way up wight he pushrod extended. The pushrod was so loose you could rattle it around. I disconnected the coil wire and bumped the motor around little by little to check the other pushrods. None of them came close to ever getting as loose as that one. all maintained at least a slight bit of tension even when fully up. I assume this means I have a collapsed lifter. This sucks because I just built this motor and I really don't want to pull the intake. I will probably go ahead and invest in some roller rockers. If i have to take everything apart I might as well.
