I have a 340 in my 67 Barracuda that came out of a Duster (not sure exactly what year, I've been told 72 but maybe a 73) but that irrelevant because the heads on the motor are not the originals, the car came with an extra set. The heads bolted to the motor are both (360) J Heads, casting number 3418915, AAWJ. The date codes are what's throwing me from identifying what they are and I'm trying to determine what valves were originally in them. Yea they could have been machined but they are on the car and will not be removed anytime soon.
Both are date marked 0967, this would be Sept. 1967 right? From everything I've been reading on other posts here is that the "915" J Head wasn't molded until a few years after the, 70-71?
