I just purchased a 429. One head is a DOVE-C, the other is C8VE-E. I researched and found that cumbustion chambers and valves are the same, and they look like the same head. Will they work together? Was also wondering what compresion ratio will I end up with. The block is DIVE wth .030 over standard (oval dish) pistons. Thanks for any help.

 

C8VE-A & E – 1968 was the first year for the 385 series engine. The 429 was introduced in ‘68 Thunderbirds as the "Thunderjet"...the 460 was introduced in the ‘68 Lincoln line up simply as “460”. These heads have 75cc to 77cc combustion chambers. They will give about 10.5 to 1 on pre-'72 blocks assuming factory type pistons...9.5 to 1 to 10 to 1 on later blocks with increased deck height. The Thermact-air boss and passages were not drilled for 49 state emissions. The Thermact-air boss is slightly smaller than on later castings. Like all of the BBF castings the exhaust port needs a lot of help. The heads used positive stop shouldered rocker arm studs and cast iron rail self aligning rocker arms at 1.73 to 1 ratio. Valve sizes are 2.09" intake and 1.65" exhaust.

C9VE-A is basically the same as the '68 unit. Used beginning with the '69 model year vehicles...includes engineering revisions to the '68 casting.

D0VE-C – D0VE heads were a revision of the original casting. Used beginning with the '70 model year through the end of the '71 model year run. These are similar to the preceding listing. Slightly larger Thermact-air boss...all 3 being used for passenger cars. D0VE-A is a less revised version and very similar to the D0VE-C's. The cylinder heads used from '68 to '71 are interchangeable as sets. Mixing castings types will vary.

I might suggest that you look for a match for one or the other of these heads...just for consistance sake. They do have differences between them.

Hope this helps.

 

Thanks for info

 

I have one bare D0 head in my basement. My buddy had them checked for cracks years ago and on ehead was bad so he gave me the other. I know it's good.
