L89 heads installed at dealer -68

[black69]

is it possible the l89 head option could have been shipped for install at the dealer? i know the odds are unlikely, but had to askl.

Nope.  Engine would be coded as an L78 (or whatever it was) when it left the engine plant.  Dealer or a previous owner could always have installed a set of over the counter aluminum heads, but the engine would not be coded as an L89
