351C oil restrictors

Is it absolutely necessary to run an oil restrictor on these 351C motors. I've heard its a wise idea if your really using the engine hard but isn't really necessary for a mild street engine. Any thoughts, Now is the time, I'm done cleaning the block and have begun assembling the pistons. I'll be placing the crank in tomorrow

I don't expect a mild street engine will have any problem.

If I had the engine apart, I would do it. Nothing worse than damage done when it could have been prevented with an inexpensive part and a small amount of time. It is a wise Idea. Do it and sleep easy. My 2 cents.

Only use restrictors if your using a solid cam! Its right on the instructions.

You can use restricter on hydraulic lifters. Never hurt my 351c. Mustangsandmore.com has good info on this subject.
Definately worth considering that kit that takes oil from the pressure sensor port and routes it back down to the port in the block beside the gas pump, MPG makes them. I wish I had done it when the engine was out, I may still do it now it is in.
