It is important to orientate the outer valve spring of the intake and exhaust (See Fig. B & C) with the *tightly wound coils on the bottom. THE ORIENTATION OF THE INNER INTAKE SPRING IS NOT CRITICAL.
*Note: To figure out which end is the tightly wound end start at the end of the coil. Follow it around 180° (See Fig. D) then look at the distance between the two coils. Now follow the same steps from the other end of the spring. Whichever end is closest together needs to be on the bottom.
