Good Morning, I'll chime in on this a bit. Have you determined if it is cam or crank rpm based. If cam rpm... have you listened to the fuel pump yet? They have been known to make sounds like this. If it's crank rpm based... When does the ticking start, cold, hot, when revving up or winding down? This should lead to whether it maybe a piston or rod sound. Well just trying to help. Seems to me if it was there before all the work was done and it's still there, the fix would be something entirely separate not yet addressed.

All have a great day, God bless, Terry
