Ticking as the engine is reved higher, or put under load, sounds like an exhaust leak not a lifter.

I will double check that too. Might need more grinding so the manifold can fit. I also have that heli-coiled exhaust stud and probably could tighten that nut a bit more. The noise doesn't sound like that to me, but what do I know haha. Wouldn't be the first time I'm wrong about something haha.
