I can't imagine what would be holding someone back from ordering either the TF 240 or 270 heads if they were building a combo where this is the type of head that will get the job done for them.

They aren't going to be substitute for a B1 head, or some of the bigger Indy heads, and probably aren't the best choice for a high cr big cube bracket motor where someone is looking to make 800hp+.

But if you were looking at "comparable" heads, and had these on your list of possibilities............ I can't see any reason not to pull the trigger.

Like the 240's, these heads are going to be very hard to beat from a power vs cost vs build quality standpoint.

There are other heads that will make just as much power(or more), especially if the motor is bigger and the combo is "racier", but it's going to cost more to get into them.
