Need help, Piston squirters modification

[totle]

Hi,

I have a 1971 2.2 911T that came with a 914-6 project I bought from California.
I was told the engine was upgraded, but owner did not know what upgrades it had. It was built by a former employee at vasek polak in hermosa beach


I have taken the engine apart, and it has S-pistons, S-cams, webers, and Mahle nikasil cylinders.

I want to do the oil bypass modification and install oil piston squirters.

My friend has a machine shop with all kinds of fancy CNC machines.

Does anyone have a description of how to drill holes for the piston squirtes?

Would be grateful for any help here

BTW, if anyone has the matching chassis nr, I will be willing to sell it to help make a matching number car back to life
Engine model/number: 911/07 ,#6109506

Ask cgarr (Craig) here on the forums. He's done that exact job (both the piston jet bores and the oil pressure bypass modification) on several older 911 cases.
