So I posted progress and the finish of the head job and every had been smooth sailing.
Head has been retorqued and reset valve lash all was good.
Today I took it from lvl 2 to lvl3 and hit the highway for a little rip and rolled into the throttle from 1800-2500 and got a tap or slapping sound from the engine area and I immediately let off and the noise went away. Turned around came 2 miles home no other noise but I didn’t lay into it.
Head was resurfaced .12, valves ground down, 103lb valve springs new seats , new seals

Maybe piston to valve contact?
Injectors or injector line?
