For a cam and street use, try a stock 340 cam or a step above it with a set of rhoades lifters. Stay in the 260°/270° range, stay below 280° duration on the cam.
If you choose to run headers, do your homework. I used to run the Hooker super comp headers, but they hang too low. They bottom out on curbs and speed bumps and crush the tubes approx 70%. I went back to stock exhaust manifolds because they would get so restricted from crushing them, stock manifolds then had better flow and didn't get crushed. a good set of headers will have better flow if they don't get crushed with driving.
