just bought 2 460 motors and i have 78 f150 4x4 with 351m, my question is the 1 460 is a 71 model with apparently 2 diff heads on it, passenger side says dove-c and driver side says d3ve-a2a, then the other motor which is a 74 says c8ve-e on both sides

 

anybody tell me why the 1 has 2 diff heads?

 

Try your question here:
460ford.com

 

The DOVE-C heads have a 75cc combustion chamber and nonadjustable stud mounted rocker arms.The D3VE heads have 95cc chambers and pedestal mounted rockers.You have an engine with different compression ratios for each bank of cylinders.The C8VE heads are 1968 75cc chambers and nonadjustable stud mounted rockers.These heads will raise the compression ratio on later model low compression engines and would benefit from some porting,especially on the exhaust side.As said 460ford.com is a great site for 460 info.

 

ty 4 info very much

 

the 71 has dove-c on pass side and drivers side is c8ve, i had it wrong, and the other motor, has both the dv3 heads, anyone know how many horse the dove c and c8 headed motor will push, i was told it also has a mild cam in it

 

The c8/c9/d0/d1 ve heads are all pretty much the same. Switch out the studs for chebby style adjustable ones, port 'em, use bigger valves and hardened seat inserts, put a nice cam with it, and enjoy the compression! Stock truck engine w/these heads gives about 9.5:1, with a little porting probably good to around 450-500 HP/530-550 TQ. Have fun with those heads, they are a hot commodity!

 

does it matter 1 side is c8 and the other dove-c ?

 

No it does not matter, basically same head, different year. Engine won't know the difference.
