I have an old set of double hump heads. I really don't know much about them, so I figured I'd ask around ! Anyways the casting numbers by the valves are 3782461. Although on one head under that number it had D245 and on the other head it had A196, dunno if those numbers matter. Thanks alot.

My Dad has had them for a long time just never used them. He had them checked for cracks already . I have to run a stock head on my Street Stock I am building, so I figured I would use them since I have all the hardware off the Bowtie heads that came off his old car (valves, springs, studs, etc.). Thanks for the input. Plus I have to run a cam with no more than .525" lift .

I agree with Flatlander.Here is some additional info,according to my casting number book, they were made from 1960-66.Originaly installed on 283's and 327's.62.1 cc chambers.....I believe they are considered to be some of the better stock heads.

Hey Hrace,

I believe these heads have a 64cc combustion camber which is alot better than the smog heads. Only problem with these heads is that they don't have any accessory mounting holes on the front of the head. For your power steering or alternator etc. But this can be overcome. 34Racing
