which intake should i use?

i'm not looking to build a killer combo, like i said, i don't care , just playing around. i get bored very easy and like to change things up, once again, thanks for the input. next plan is to build a 408 with 308s or xheads, with this cam already broken in. Please don't recommend aluminum heads , i'm in my 60s, i'll do it old school.

I am in my 60’s and aluminum heads have been around since the Jurassic era.
Why somebody would want to use something that will create a bottleneck to making good power is beyond me.
If you truly want to have fun, get a good set of heads and an 8 inch convertor. They will be enough to allow for mistakes with everything else
