Are you sure you are comparing apples to apples? The EZ head isn't MW size unless you buy it that way and it is more expensive than the entry level head which is unported.

I have both heads and the TF head is much higher quality out of the box. You can't run the Indy head out of the box, it has to go to a head guy who takes it apart and fixes it. The guides are sometimes super loose in the Indy heads or the valve job isn't finished properly. The TF heads are very nice right out of the box. Still a good idea to take them apart and double check everything but you most likely will not need to fix anything.
