let's face it any 1960's head and port design is flawed, just some are less flawed than others. even the vaunted 426 Hemi is flawed. truthfully, the naturally aspirated V8 engine is flawed, for that matter. it's loaded with design compromises. the intake and exhaust flows both ways the whole time it's running. it takes a supercharger, or turbo to patch the big holes in the way a NA engine breathes, because it runs in spite of itself. that's why so many newer 4 cyl, 6 cyl engines are using turbos now.
back in the 1940's practically every military fighter, bomber used turbos or blowers. they wouldn't be caught off the ground without it, or they'd get shot down in flames. it seems like the car engines are moving in that direction today as well.
the tunnel port did a great job competing against, the beating the Hemis on many occasions. it also won Lemans in France. it's arguably the best inline valve wedge head ever used on a V8.
