I have a very similar build, minor differences. Made 430 hp and 330 tq. I have a very similar noise (lifter?) coming from the left side valve cover/VCT solenoid. Shop I was tuned at (PSI in Portland) diagnosed it as a VCT sensor going bad, which may be what you’re experiencing. Try unplugging it and see if it goes away.
