Hi all, I've been trying to track down an engine noise that sounds like lifter tick but have come to an end and not sure where exactly to keep looking, engine is a 97 block with 2000 pi heads, comp cams, BTR springs and retainers, new lifters, new ford gt followers, new timing chains and guides, new tensioners. But the noise is still present, I check out pressure out of the cam cap on passenger side, the driver side is a pain to remove the valve cover due to engine being in a 79 mustang. New Ford racing 4v oil pump as well.

Engine was running and sounding good then started tapping. I'm at a loss. Cold start oil pressure is 90 psi and hot idle is about 35 psi. Can someone point me in the right direction here please, engine sounds like a solid lifter engine.
