B1 heads are odd because they don't flow enough air relative to the port size (or CSA: cross section area) on a big inch combo the port is big enough to support the cid but the flow isn't there to support RPM so the engines tend to nose over early.

Thats because they are a wedge and have limited valve size, right? Does the TS also lack flow for big inch motors?
