Time spread in Winters cast heads?
 

I am asking for opinions on how much more of a time spread should be expected for 842 L89 heads cast by the Winters foundary compared to 840 L78 heads cast by Tonawanda (sp)to then be installed on blocks cast the same day. With the much lower volume needed for production of L89 cars, surely Winters wasn't casting these heads every day and would have had short casting runs to keep ahead of Chevy. Or were they a small enough operation that daily production was what they did? I realize they were casting aluminum intakes among other things at the same time and I would guess at the same facility.

Loren,

I don't have a direct answer for the spread, although I
would think that up to three months might be acceptable.

I would say the the "rarity" factor might not be that
in-play here. I've seen tons of 1968 & 1969 dated '842
heads on eBay over the years. Remember that they were over
the counter items as well. I'm betting that lots of them
were purchased by racers back in the day to lighten up their
cars. As you noted, not that many real L/89 cars out there
and I'd have to believe that most, if not all original L/89
cars have their original heads due to the value they bring.
