Probably about time-rocker adjustment

The other guys were basically saying if your lifters have a retaining clip in the top, they were hydraulic. That's not necessarily true. There are also solid lifters that have a retaining clip as well and are almost indistinguishable from a hydraulic lifter upon visual inspection. So make sure you keep us posted with what you find.
Post 17 has pic of top of lifters. I might remove my intake tomorrow to get a better look at things.. That or with a magnet try to get a lifter out. I am pretty sure they are solid. They do not compress at all when I tried to push down on the pushrod. I did not go crazy and push down very hard though. What started this all is the engine seemed to be noisy at around 3000 rpm's and seemed to be down on power. After removing rockers and pushrods I found one PR was bent. Since I do not know the cam specs I do not know what the proper valve lash is supposed to be.
