Similar to SUPERSIX intake manifold?

do you know of any slant six preformance intake manifolds that can be used on the street? I've been looking at the hyperpak manifold from clifford preformance. But i feel that that is just a little to much. Also the supersix setup, but i have tons of trouble finding those intakes

i have a aluminum 2 barrel you can have for 20 bucks plus shipping. Tried to polish. Looks like hell but....... The heat area has been welded close. Good manifold.
