Re: Earlies date for 3964291 L78/L72 heads?
I saw the ad for these on Ebay. This is the 3rd set of this style '291' head I've seen. I think these must be '78 or maybe even (though doubtful) `88 castings.
I saw a set like these that had a casting date something like 'E080' which would not be 1970, as those 70 dated heads had 70 as their casting date, not just an 0 for the year.
Hope I haven't confused the situation.
Notice the 'CFD" that is not on the original style 69 thru 75 castings. Also the casting number '3964291' looks completely different than the early design.
