Wanted - Early 840 Head with temp boss undrilled (May '67 preferred)

[Chevelle SS 396 L78]

I’m in need of a 3919840 Rectangular Port Hi-Perf Head with the temperature sending unit boss not drilled for my 1967 L78 Engine Build. Please message me if you have one (just one). My build will be on hold, sadly, until I find one!!!

The head I already have is dated E187, so anything near that date would be perfect, but honestly, any May '67 cast date would be great! Next best thing would be any 840 head without the boss drilled (regardless of the date).

If you have two, that would be considered as well, but I'm not holding my breath! LOL!

I really appreciate any help on this!

Thanks,

John
