I have a similar tick that decided to show its face one day. I was driving next to a retaining wall and heard it. Not knowing what it was and not being able to pinpoint the source I decided to tear it down and find out if I could find the source.
I replaced the lifters (and with a Whipple this is no easy task) checked the cam while the heads were off, checked the valve to piston clearance and the valve springs and did not find anything. I replaced the valve trunions and guess what. Upon startup the tick was still there. The car has 10,000 miles, 4 with the build. I have purchased a stethoscope to find the source or at least help find it, but with all the noise under the hood it is impossible by ear alone. I suspect it may be an injector going bad as I have gotten some lean run codes. I love a challenge.
