Problem with the cylinder head, 16v 1992

[fixkick]

Hello !, I mounted a sidekick engine on my samurai, the motor was completely adjusted, valves were regulated (0.13mm) and it has this sound, which could be, any help is appreciated

noises are near impossible to diagnose remotely , even with youtube sounds
sad to see the poor MAF like that bouncing to death... (the most expensive sensor on earth too)

did someone remove the cylinder head then put it back blocking the 0.050" oil gallery front left orifice now the cam runs dry..  
never service any engine block or head then run it not checking for top end oiling, or boom , head is wrecked,  a 15min job to inspect the orifice and not put that
great Felpro gasket on backwards , this maker even marks which end is up.  if put on backwards it blocks the OIL GALLERY , port,

"FRONT" marks on gasket.stamping. do no ignore that.
off my engine or head pull page ( it unscrews with an allen hex key wrench, done at gallery cleaning step and put back)
