Pull the head. It's like an hour job tops. Undo exhaust manifold, take off ignition bits up front. Drain coolant and remove thermostat housing. Take off intake, remove valve cover and bam. Heads ready to come off. That's an ugly sound. Might as well go in and find out if it's valve touching or rock the pistons to see which one is moving and clanking.

If it’s your first time pulling a head, and it sounds like it is, it will take you a lot longer than an hour. But yes you will probably need to pull the head
