As has been brought up in the other TF thread, I really don't think the MW version of this head is going to break any new ground.......other than what you get for the price.
Whatever these heads are capable of, there is already another head available that will get the job done.

This isn't any different than the multitude of 23deg SBC heads offered up by all the various head manufacturers.
There is rarely any solid consensus as to which one of any different port volume(200,210,220,230, etc) is "best".
Different builders have their favorites, all work well.

I feel the same will be true with this TF 270 head.
If it fits the requirements of the intended build, I'm sure the results will be satisfying.

I will say that if the fit and finish of this new head is as nice as the 240 head(no reason to think it wouldn't be), for the price, they will be very hard to beat.
