When it puts an aluminum spacer between rocker arms, it is Good.

@DatsunSSS

Give us a rundown of what has been done to this engine and future plans. I must also add it looks damn nice in the red color.

The spacers improves reliability with high revs. (rockers arms cannot climb off the push rods due to the spacers instead of the springs)

The spacers will stop the rocker arms floating at high RPM.

I do recoils of screw in the cylinder head side of the locker tower by all means.
This is effective for a strong raceingspring.

I'll translate,
It is a good idea to helicoil,recoil or time-sert the rocker pedistal bolt holes..
it's reccomended if you use upgraded springs..
