Remove smog pump?

I am rebuilding the top end of a 72 240Z engine. I have an E31 head and have removed all the equipment on the block and am cleaning it for painting. (I noticed after cleaning the grease off that it is a light blue color - I never knew that!)

The last major work I had done on the car was when the Wizard of Z's (Riverside, CA) was still in business before he retired. The Wizard did a marvelous job on the engine, it really purred!

Since I didn't need to smog the car any longer because of its age, the Wizard asked if I wanted the smog tube hooked back up to the intake manifold. He said it would give me more power so I said no, don't hook it back up.

More than 10 years later, the engine has a blown head gasket, which is the reason I am working on it now. Since the Wizard is no longer there and to save money, I am doing it myself.

The question I have is, is there a reason to put the smog pump back on when I get ready to put it back together?

Thanks!
