I would be surprised if anybody could help me with this one. I need a single 69 boss 302 head. I need to know where I can get one. This is why. I bought my heads from semo mustang several years ago. I rebuilt my motor last year. When I originally bought these heads from semo one had a crack in it. I bought a set of 69 boss heads. I sent the cracked one back and they sent me a 1970 head in exchange. I phoned them they told me that they where the same. So After I had my heads redone last year (new screw in studs, guide plates, stainless one piece valves, roller rockers etc) I found out that the cc chambers are slightly off which frustrated me cause semo mustang said I should have known that and that they aren't responsable. Any way I am running the engine the way it is but I hate it. Cause I have spent a lot of $$$ on this motor but I wan't to fix it asap. So any feed back would be apreciated. thanks Bob

I know Dennis at www.dscmotorsport.com can get you one. I don't know if he has any readily available or how much it costs though.

 

Have you thought about having the heads matched with some bowl work? I know that means you have to take the engine apart again to have more maching work done but it is worth a thought.

 

I am looking for another 69 head. I have some posts on some other boards. I don't really like the idea about grinding out the combustion chamber. then there is the problem of the 70 head having a slightly smaller runner. grrrr. Anyway I will try and find another 69 head then sell my 70 on ebay. just means I will have to do machine work to the new 69 head. Thanks Bob.

 

Different valve sizes than the 70's also.

 

Ford downsized the Boss heads in 1970 becaused they realized the ports/valves were TOO BIG for street use (read too unresponsive). I guess it depends on what you are looking for...if you want a number matching car to make it worth more keep the 69 heads, if you want maximum street HP, responsiveness, and want to go toe-to-toe with other Mfg's muscle cars of the same vintage I'd put my money in the 1970 Boss head.
