I like context. There are plenty of end users of the Trick Flow heads with no concerns of too small of seats or bad ports. Bolt on and roll. No sinking valves, seats coming out, no need to wring more out of them etc. Engines are running great. Some of this sounds like a case of an exception (or a few exceptions) not the rule. Perhaps the exception(s) is/are simply at a level beyond what the heads are primarily geared towards. There is nothing wrong with the TF’s for a majority. IMO.
