Aluminum BBC Heads *Rare Casting*

I have a pair of '3919842' casting bbc heads.

This is what i've pulled from the heads...

~5529, Cracked, Not Ported, 9 . 3 . 67
~7537, Not Cracked, Ported, 10 . . 67

They both came from the same car, one has a TINY crack that was barely picked up when magnafluxing it.

Off of an L89 motor, can also be passed off as L88 heads.

I'm asking $600 cash.

Before you guys say i'm nuts for asking this.... These heads go on ebay all day long for 2,700+ complete with helicoils in them. I just watched a pair that was bare go for 2,200. I think i'm being fair in asking what I am.
