360 heads on a 318 of any benefit?

Why not ditch the 360 heads and go with a set of "J" heads or summit 318 2.02 heads? I will be building a set of roller heads from the summit 2.02 castings they are $525 a set I believe or in that area any ways.

Can you please provide a link? Ive never heard of Summit Mopar heads. Are the mags or LA?
