Engine Identification Please

I'm trying to figure out what motor is in my 77 f100
The only number's i can see are on the block under the head
C07x7 and the number on my heads on the inside by the intake
14706

The motor looks great .030 piston..etc..etc

I recently blew a head gasket and i'm not sure if it a 302 or modified 400

any help would be great
Thanks

6 Valve Cover bolts = 302

7 V/C bolts = 429/460

8 V/C bolts = 351M/400
