Default Edelbrock P4B

I'm building a 455 for my GTO. Typical street engine - 9.4 cr, ram air exhaust manifolds, etc...it will run a Q-jet with tweaks I learned from Cliff's book.

The only intake manifold I have on hand is an old P4B - it's in nice shape, so I could use it. I'd need an adapter to run the Q-jet. Is it worth it or should I just try pick up an original iron manifold? There is one for sale on marketplace - its a '68 casting for 50$. The drawback is it's a couple hours away. Opinions?
