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.
