Louis Tool
 

Bought one of these to elongate my pushrod holes. Problem is that the only way i figure it goes in the slot, it moves around quite a bit, so im not sure how accurate Im being. Does anyone have a picture of the proper placement for this thing? these are #62 heads if it matters.

thanks again....

Whats a louis Tool?
I have Spotts elongation tool, bolts in the rocker stud hole, yes it does move around if you are using a hand drill, works better if you can use a prill press. and high speed.

The "original' louis tool is designed to work on small block chevies mostly,not really for pontiacs,the SBC pushrod slot holds it in place better than a pontiac pushrod slot would.

The spotts elongation tool is a louis "style" tool,but it is different so it works better on our pontiacs than the "original" style louis tool.

damn... i knew something didnt look right. alright I'll get me a spotts tool. thanks for all the help guys.

I used a long rod that I got from home depot (mounts in drill) and a side cutting drill bit (which it then mounts into the rod) - of course my heads were aluminum and went faster than yours prob will...
