Action+Plus vs Stealth

Looks like the A+P is set up for a spread bore (TQ) but has the smaller ports for a 273/318, while the Stealth is set up for a square bore with ports for 340/360.
Which is the better 340 manifold?
Port the A+P or use an adapter on the Stealth?

The worthless port window consideration.... pssssstttt.... they are the same size. LOL
