DN codes a '68 307 or a '59 283 engine. Paint is blue, not Pontiac color. Cannot tell what the 48 means.

It's a shame the archive is gone.

Head codes at wallace racing. My 69 GTO w/manual trans had #48 heads.

I see. They are a key part of a project, sad they rusted so badly from a poor storage spot. Hoping tanking can clean them up,

I had some heads that looked like they had barnacles growing in the runners! They cleaned up good. Porting goes way beyond some rust pitting....
