Should I Buy the following and piss off the wife??

A guy I know in my area is selling:

Pair of Eddy aluminum 60779's, they are brand new, I remember when he bought them and he never used them.

He also has a air gap, brand new, same deal.

He is asking $900 for the heads and $175 for the air-gap.
Summit sells the heads for $720 a piece plus shipping to canada.
The intake goes there for $264 plus shipping.

My question is, is this enough of a deal to be in the doghouse for quite some time?lol Or is this an average deal that can be had again? I could use the airgap right away to replace the LD340 on my 360. The heads I would save for a 340 block stroker and that build is not happening for quite some time.

I think this is a decent deal, my wife however, may concour!
