The early B20A heads have a very low exhaust port floor all the way to the manifold surface. The late B20A and the injected heads have a somewhat higher port floor at the valve side, which goes down to 'normal' height again at the manifold surface. The late heads therefore have -at least some- short side radius. Now, one (simple) questions: which one would flow best?

cheers, ben
