6. Install the new valve plate by aligning the indicator hole on the plate to the discharge valve. When properly
installed, two holes will cover the discharge valve and two holes the head is visible. If you cannot see the
head on two adjacent holes, the backer plate is not installed properly.
7. Lay the gasket without material in the center on the backer plate. Align the two indicator holes.
8. Place head bolts into two of the holes to maintain alignment of the gaskets and plates and install the head
onto the cylinder. Hand tighten the four head bolts. Then rotate the crankshaft to verify the piston does not
hit the head. If it doesn't hit, torque the head bolts to 150 to 160 in-lbs. (17 to 18 Nm) and recheck. If the
head does hit, return to step 3 and realign the cylinder.
9. Remove the old compression gaskets on the crossover tubes and replace the compression gaskets. Then
install on the first head using a 3/4" wrench. Do not over tighten.
