How to make oil restrictor?

[zombezoo]

I know you need to run an oil restrictor for the oil feed to the head, but how do I do that? I plan to drill and tap another hole in the oil distribution block and route it to the side of the head but where do I put/make the restrictor?
Thanks!

You could snag the one out of your block (not being used anymore). It is taperd and could be firmly inserted into feed line.

I made mine from one of the original oil fittings that screw into the front of the block. Basically I just cut it shorter, plugged the original hole where oil flowed into it and re-drilled it to 9/64" . Then added the extra flare fitting for the oil supply to the turbo.
You can see where I put this fitting in my other post with the engine pictures.

You need a fitting in the head to run your oil line to, right? I threaded the INSIDE of the fitting, put in a plug, and drilled to the appropriate size. You could also weld it.
