They are #14079261. What little I can glean off the web successfully is they are 1986 350 SBC heads for a pickup, I've seen mention of implying they are related to TBI, and quite a bit of single year, so I am starting to guess after all my trucks engine could very well be the original, minus the manifold with a metric ton of silicon on it in place of an actual gasket.

Sounds like they are 76cc, early swirl port heads. Nothing special. First year of different intake bolt angle.
