Phew, just cranked her over and she was noisy as all anything. Topped off coolant. Cranked again, repeated about 5 times as it slowly rose to temp. Let it run for five minutes and the clanking faded. I guess the lifters needed to pump up. Gonna give her a couple more starts then change the oil back to synthetic. Man, pulling the heads are always such a pain in the ***! Hopefully this will last ne another month or two till i do the planned headswap. Ill replace all lifters that time (only did four this time). The cam didnt look too beat up, but illl inspect it and see how the lifter is before when I pull the heads. If it chews through another lifter, ill put the stock cam in and have to order a new cam. So far so goo though... The intermittent ticking is gone.

I left my engine in the car and took the heads off. Fairly easy, but time consuming. About three days worth of work by myself. Check out ls1howto.com for a good writeup on swapping heads.

I am running Patriot Gold springs, with a fairly stout cam. I am wondering if these stock lifters are problematic with stiffer springs and high lift cams. Mine is a 598/609 lift.
At first, I tried the oil detergents and that only helped for less than a day, then the noice came back. I too thought it was an exhaust leak, as well as the exhaust rattling against the chassis.
Even though the pics made me sick, I still have to say thank you much for your post. It was *VERY* informative and helpful.

Head gaskets are ~25 for the MLS GMs. Bolts are about 30. Plus a jug of dexcool is like 12 bucks. It may take a couple days to pull the heads, clean and inspect and then reassemble, but the sooner you do it, the greater the chance of saving your cam. Ive put on about 1300 miles since i pulled the heads and so far everythigs holding up. I plan on swapping heads again soon, so i can check to make sure the cam is not getting any worse at that time. Good luck man, any questions, just post up!
I just can't get out of my mind your description of the ticking sound after you shut off the engine...that's exactly how mine sounds with this problem.

Yes, same cam. The pits werent nearly as bad as the picture made them look. Could hardly feel them. They wernt flaking like the lifter rollers were, it looked like it was just slightly scratched from coming in contact with the rough lifters. Only that one lobe showed any pitting, and the nose that was shown in the picture was the worst of it. I know how you feel about having it cause another lifter to come apart, but i figured ill be doing heads soon enough anyway. I wish you the best of luck with it, but dont drive it if possible till you pull the heads and see for yourself.
