It says "Grub Screw".

I have the by-pass filter on mine, and I was surprised at how much oil does flow through it. I could see the return squirting back into the fuel pump stand and the beehive filter was quite hot - that means to me that the hot oil was flowing through at a decent rate to make it heat up like that.. If there was no flow it would be cold, so the hotter the better - and the fins act like an oil cooler when the car is moving along.
It does have the 1/16" restrictor.

My other engine has no filter. Don't do enough miles for it to be a problem.

I might try the setup above on my next build.

One important point to make - I know this has caught someone out because I read it on one of the forums - If you are not running a filter, make sure a previous owner has not modified the block like above - likewise double check if it has any military history, because the passage where the grub screw has been fitted needs to be open to run filterless.
