If anyone is interested, i have a set of #8 heads i can rebuild and sell for very cheap, and an intake that matches, quadrajet intake off same engine. cant remember what year the motor was exactly, but i took the entire top end, and am keeping the stamped olds valve covers for myself lol.

 

If it had the stamped covers it was a 73 or 74.

 

#8 would be '55 heads I think. can you post a photo of them, how complete are they and where are they?

 

#8 are 70's SMOG heads, same as on my "74"

 

411929 casting made from 73 to 76 and are 79 cc
