Hi Jake-quick question on the date codes. Since these heads were cast with the Julian date codes of DEC 12 and DEC 17 (non leap year
http://www.348-409.com/numbers/hdc.html ), are you having to extrapolate that they’re 1962 heads since production of 690 heads apparently ended Nov 12 1963? That makes sense, but I’m wondering if there’s any way to tell ‘62 and ‘63 castings apart if the Julian numbers were, say, October dates instead. GLWS
