Checked valve lash as you suggested. #2 intake both, and both #3 exhaust, are out of spec.02 inches or.5mm. Should I change shims as ticking goes away after about 1 minute of running? Thanks
Do you
have the same problem?

If the ticking goes away in about a minute I would say change the lifters you may change the shims and still have the same problem as it may be those lifters are bleeding off.

They are not solid lifters they are hydraulic lifters that use a shim to set the clearence to the cam lobs. See pic below first pic you see the center plunger the second pic you can see the oiling hole in it. They can bleed off.

Thanks racefan966. I think you have the answer I was looking for. The lash was out.002 inches instead of.02 as I had said earlier, but the hydrolic lifter bleeding off would make more since, as the noise stops when oil pressure comes up. Thats why you are there with the answers and I am here with questions. Thanks again

Well each manufacture makes them slightly different. It is still a hydrolic lifter so I would replace them and set the gap. Soak them in oil for a few hours prior to installing.
