Hey Guys, I have a 68 400 (YT block) confirmed by PHS - but I am trying to determine what heads I have. I have identified two separate codes stamped on my heads;
1. EO 18 (stamped on driver side heads ) and 2. D2 68 (stamped on passenger side heads).
I assume that the EO 18 is the head casting ID but this indicates that I have 350 HO heads - which is not on my PHS could mean that someone swapped heads? Assume the D2 68 is a production date code of some sort. Any guidance on this?
