Installation Procedure
1) Remove the stock head and clean the top surface of the cylinder.
2) Install the domes and all orings in the ADA billet head. Use grease to hold orings in
place, do not use glue or gasket sealer of any kind!
3) Install the ADA billet head onto the cylinder with the water outlets on the carburetor
side. Make sure that all orings stay in place and do not come out of their groove,
causing them to get pinched.
4) Install the stock nuts and washers, first torque to 15ft/lbs then to 18ft/lbs. The
torque pattern should be done the same as the stock head, center of head outwards.
Re-torque the head bolts after the initial use and then periodically thereafter.
5) Water routing can be done different ways and careful experimentation is recom-
mended. However, it is best to start with the stock water routing or if using an af-
termarket exhaust system, the recommendations of the pipe manufacturer. When
experimenting with water routing, always check front and rear cylinder temperature
for consistency.
6) If you are using a girdle head, please follow the instructions that came with the ADA
girdle kit for girdle installation.
Read First!
Please read these instructions completely through before starting the installation. If
you are also installing a girdle kit, read those instructions beforehand as well.
Please note that the ADA billet head is installed with the water outlets on the carburetor
side of the engine. The ADA billet head does not use a head gasket and must be in-
stalled with the outlets on the carb side for proper cooling.
Do not use silicone or gasket sealer on any of the head surfaces.
