Re: 66 C20 327, green original engine paint

Could you post a picture of the front end of each head after they are grease removed? I think I can just see it's there but the drivers side head could have like a "YH" in yellow grease pencil on the front of it indicating 327 turbo 400. Interestingly it may have something as Y_ as it also has the A.I.R. calif emission but no code appears to have ever been assigned in the GM books for that one. Cool to put that back on there when you have it all painted up again! Also were you able to see the codes on the firewall with assembly line grease pencil for the options like the turbo 400 tranny? My 327 turbo 400 donor parts truck had M49AG written just to the right of center upper firewall and before the drivers side washer hose cowl hole. Sometimes those marking are very faint but still readable in the right light.
