COPO LS7 CNC Head
All the same high-flow attributes as the assembled head described above, but delivered unassembled. Valves and valvetrain components must be purchased separately.
NOTE: All COPO 350 and 396 racing cylinder heads are built with the same “Max-life” valve springs and hardened spring seats as the 327S/C and the 427 N/A, plus, they include light-weight hollow-stem LS3 intake valves and light-weight LS9 hollow-stem exhaust valves.
