RB 26 sound input help

[Evolved_St8]

Hey RB Gurus,  My fresh built RB26 is making an interesting ticking noise from the head.  Valve Lashing has been checked and is supposedly perfect.  Sound is definitely coming from the head.  Take a listen and let me know what you think?

Is this better?

Take off the cam covers and inspect the cams, sounds like either there's not enough oil going to the head or your head hasn't been shimmed correctly.

Shims have been verified.  And the cams seem to be good.  The head does have the restrictor in it, but the car has N1 oil pump w/ boundary gear.

How much oil pressure do you have?

Dummy gauge in the dash looks good.  I havent been able to install the haltech sensor.

Have you looked in the oil filler or taken a cover off with the car running? Try to assess the pil pressure and pinpoint the sound better.

I haven't, but thats not a bad idea.  I suspect the sound is coming from the intake cam side so that may very well help.  Its quite a bit of disassembly as I also have the hypertune Baffles.
