76 3/4 Cheyenne 350 build

My 350 4 bolt is going in a 76 Cheyenne 3/4 truck, it's being bored 0.10 more as it was already .30 over, I have pistons and rings a Edelbrock performer intake and 882 heads. What size cam would you recommend? I have a Holley 750 double pumper, is that too big for 10.to 1 compression ratio? I'm also running Hooker headers, my heads are 882's, they have fairly big runners , any suggestions as to what to do to the heads? Any help would be greatly appreciated, thanks for your time.
