CYLINDER HEAD ASSEMBLY - REPLACE/REPAIR
Install exhaust valve service seats in the same
manner described for the intake service seats,
see STEPS 5b through 5j above.
If it can not be accurately determined that service valve
seats have been ground only once after initial installation,
replace the seat.
7. GRIND VALVE SERVICE SEAT(S). GRIND SERVICE
SEATS (15) FOR A FEW SECONDS ONLY TO
AVOID MAKING THEM TOO WIDE.
Valve seats marked with two Xs on the cylinder
head have service seats installed. Service
seats, like the parent metal seats, can only be
ground once after initial installation.
Grind service seats in the same manner, and to the
same tolerances, as used for grinding the
integral seat in STEP 4 above.
