Is there any reason for there being a hole cut on each side of this head of a b16a2 motor in between the cams on each end in the middle of the motor? Oil flow or something? I can tell it isnt original Im guessing it was dremel'd out but im not sure what for.
Anyone know what the deal is? Thanks guys.
Also if anyone is parting a head out i need the cam cover thing thats all the way to the left for the exhaust cam. Mine broke/stripped for some reason pulling the valve cover off.
Thanks again guys.
