TF & Speedmaster Flow Tests

All of you guys digging deep into the TrickFlow heads are awesome and much appreciated! These threads really get a guy thinking and learning. With that said I'm curious what the actual expectation is for the TF heads? We are finding theres definitely room for improvement or places they are lacking but the few racier type combos we've seen seem to run pretty good for something that doesn't need sent out for port work right?
