Sounds like hydraulic lifters. Try running some engine oil treatment in your engine.

it is your lifters, they may be spaced out and when the piston pumps, your lifter hits your valve and it will make that noise, it also couldn't just be one. you have several on the engine head. same thing happen to me. may need to go get that checked out.
