The V-6 has cross-flow heads (intake and exhaust on opposite sides) which helps a lot with scavenging. That's the biggest drawback of GM's straight 6 and why Fords always outpowered 'em.
The V-6 is basically a 350 with the rear two cylinders missing. They use the same pistons (NOT rods, they're different) and an odd-fire crank. Hydraulic roller cams are available for 'em. I have a '91 shortblock and pair of later model heart-shaped chamber Vortec heads and a carb intake, it'll find a home...someday.
Stick with the V-6, more power and aftermarket support.
