200 BENCH PROCEDURES New cylinder heads have been produced in November 1996 which have 20-degree intake valves and seats. These valves and seats replace the 30-degree intake valves and seats in all E7 cylinder heads. The 20-degree valves and seats are 100% interchangeable with the 30-degree valves and seats, provided the seat matches the valve (20-degree seat with 20-degree valve, 30-degree seat with 30-degree valve). Remanufactured assemblies will use either 20-degree or 30-degree valves and seats on certain applications (never mixed in one head). See the following chart and figures to identify your assembly.
