Well, if your definately hearing the noise on top the motor and not through the oil pan then maybe you have excessive carbon build up in a cylinder. Maybe you have a weak cylinder, bad plug or wire?? Worst case is a bad wrist pin and those are usually more common in 3.1's. Sometimes exhaust leaks sound like a tick as well. Take all this with a grain of salt, I'm just throwing it out there. 
I purchased some Manley push rods form cgp. They are currently in the car. Does anyone know if they are different size than stockers? I did a compression test little while ago and 150# across the board. Guy on cgp had the same problem, his issue ended up being valve guides. I had all new valve guides put in the heads before they were installed. I dont *think* that is the problem. If it were valve guides would the compression still hold 150psi?Whatever it is is deff. coming from the top of the engine.
Yeah, the car is a pleasure to drive. It runs very strong and gets looks everywhere. It's this damn ticking sound that is hard to indentify. If I have to tear the heads down again I will more than likely de-mod the car and sell it. Thats the last thing I want to do, but where do you stop dumping money into the thing. Every time I go WOT I just wait to hear something pop, snap or break.
Yes there is. I seen up to 10* of KR in my last scan before taknig off the belt. When I first put on the 2.8 I took the car up to 120mph with ZERO kr. I have the s/c belt off right now. Its running rich. Thats just a tuning issue, too much fuel. That will be resolved after this noise is treated...
