I honestly don't build a 350 anymore without at least vortecs. I've built a few with aftermarket heads in search of more oomph, but given how cheap vortecs are and how much better they are than even the best pre-vortec head, no contest.
I buy up cheap vortecs when I find them and just stockpile them. Worth every penny on a street SBC
