Time spread in Winters cast heads?

[nuch_ss396]

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.
