Maybe because they are unobtainable? Not to mention not everyone may agree with your assessment of the bloomer head. I for one would rather try something else which is why I went with TF’s which I believe are the best out of the box street head.
Nothing to not agree with. They have proven to approach 700 horsepower based on track results.
At the end of the day, that is where the results matter.
On my personal street strip car i
have 1.5 years on them thus far. Flawless
Super high quality castings, exceptional finish work on the castings at a high end shop( BES/ Bischoffs).
Frankly, the Trick flow isn’t anywhere near as good a head.
And they aren’t unobtainable. Last time I talked to Rod there were 10 sets in the works. Wasn’t that long ago.
