For one this does not come with the steam vent blocks in the rear and 2... after unthreading it 1 time it stripped out.. for 66 dollars I'd expect this to be sturdy... especially from ict billet... but the 20$ one did it's job perfect

Work great, they don’t leak so that was a plus for me. Easy to install also.Edit: after having to reinstall on new heads, bolt broke off in the head. Bolt seems to be made of cheap material.
