RPM Gap Intake - should I or not??

[gchemist]

I'm itching to finish cleaning out my garage floor. I have a new cabinet where I stored everthing buy my tools and a few large items. Engine stand, dropped leafs, unfinished traction bars, intake and aluminum radiator with electric fans.
Since I have to drain the cooling system to install the electric fans and radiator should I install the RPM Air Gap intake on the 305? Or should I just offer it up for sale? The new engine will have center bolt covers I won't be able to use this intake anymore. I'm itching to go racing with the fans installed too.
