Hey, can anyone out there help fool who loves to tinker? I'm trying to play with some old junk, and I need the help of someone who has a head off of a y-block. Can anyone give me the measurement of the head, from the center of one cylinder bore to the next, and from the exhaust pushrod to the intake, and to the next exhaust, starting at the end (and can I assume the back half of the valvetrain is just a mirror transposition of the first half?)
