I recently built a 360 for a guy here, using KB 107's, stock heads with stock valves, no port work. Stock rockers, DEH 275 cam, comp. was 9.4:1, performer intake, 650DP holley, and cheapo Hooker 1 5/8 headers. It made 350HP at 5500rpm and 390's TQ! And it also made 363TQ at 2500rpm. Not bad for a cheap build.
