drilling 1.6 pushrod slots
http://www.jegs.com/cgi-bin/ncommerc...76&lastcat=537
Thought you guys would like this
"This tool was designed to simplify the modification needed when using 1.6 rocker arms on SB-Chevy heads. It allows you to use a hand drill with a 5/16'' bit to elongate the pushrod slot exactly in line with the existing slot, thus eliminating the need for guide plates."

good post
good post because a lot of people do not know that you must make the push rod slots longer in the heads when switching to 1.6 rockers because the push rod seat in the rocker is closer to the pivot point.

Re: good post (clem zahrobsky)
Why does the idea of grinding / drilling the cylinder head WHILE IT IS ON THE MOTOR not sound like a smart idea???? :confused: :confused:
Where are the metal shavings going to go ??

I placed and wedged paper shop towels around the surrounding areas and over the valley. I drilled the holes over size one at a time, each time using the shop vac to suction up the shavings and replacing the shop towels as I went along.
Grinding the slots is a lot messyer(sp?). The grinding dust can travel several feet easily. The best bet there is totally cover everything and tape the edges down. Vacumn off the dust and wet wipe when done before removing the coverup material.
