I’d like to hope valve seals are good as the head was completely rebuilt. The cap dances to a regular rhythm of puff puff puff in sequence with it idling and increases as you rev it up.I'd say either rings or valve seals. Did you pull the oil cap with it running and put your hand over the hole to see if you can feel any pulses? Does it push out the dipstick? Just curious if the cap was jungle jiving it from vibrations.
