2G Valvetrain Noise

[shaunp]

Hey guys the car is making a weird tick/knocking sound. It sounds like it's coming from the head.
Background on car:
Precision 6262
Walbro 450
FIC 2150cc
Fidanza Cam Gears
JMF Intake Manifold
DNP T3 exhaust Manifold
ETS FMIC
Meghan Dp
Thermal Catback
Brian Crower 276 Cams
GSC dual valve springs with titanium
retainers
Brand new GSC lifters (installed today). I submerged the lifters for 24hrs and then bled them per GSC instructions.
Any help/suggestions is much appreciated.

when did this start? sounds like a collapsed lifter almost, but the frequency almost says bottom end/rod knock...after checking a few more videos, im almost sure its the beginnings of rod knock. check the oil and filter for speckles.

Sounds like knock to me. Id do what ThunderChild suggested and check the oil and filter for shavings.

Compression test it if you can and let us know the results.
An old mechanics trick on rod knock is to pull the plug wires off 1 at a time and then focus on the cylinder that drops the least. Some times the knock will go away when you do this test and it normally indicates a bad rod bearing when you take the load off.
Good luck! Its hard to pinpoint on the video.
