Valve/lifter problems.

Collapsing lifters / valves sticking

Do you have an oil pressure gauge?

Oh. That's not good. Not good at all. But makes a lot of sense.

And no I don't.

Assume theres plenty of oil in it?

If you start it, rev it out so it does that, then soon as it dies dissconnect something so it wont start and crank it, see if it cranks even or if valves are stuck, need to be quick tho as there likely sticking briefly.

It sounds more like valves sticking than lifters failing to me, but could be related and getting stuck on the ridge. If you put your hand near the intake when its making that noise does it feel like the airflow changes / puffs back at all~?
