65 barracuda no bottom end need opinions

I would try to find[I may have] some 273-318 heads and I know its more expensive but I think It'll really perform better with the solid lifter adjustable rockers. 273's came with a solid stick in 64 or 65. Mopar performance sells the cam and lifter package reasonable.I can get the part #'s and stuff if interested. i wouldn't want much for the heads if I can find them!!
