350 valves ticking?
New to the site. Tried looking at other posts and was not able to find any answers. So to start I have a fairly freshly rebuilt 350 bored .60 lunati voodoo cam with hydraulic lifters, RHS heads, comp magnum roller tip rockers. After having problems getting it tuned in (still learning all this) I took it to the shop to have it properly tuned. No ticking while I had it. Mech. tuned carb, timing, and adjusted valves. He drove it and said it was running great. Shut it off and restarted and started to tick. He adjusted one of the valves again. And it ran awesome my first two trips around town, no tick. I started it up the third time and started to tick again. He said it may be a lifter collapsing. So after a long story my question is does anyone agree with this, and is there anyway to make sure that is what it is. I appreciate any help.
