Search TB.com for casting #’s 7515 and 7148

What Champion does is install hardened seats unto the heads.. this helps stop the cracking.

The cracks can be repaired. I have had cracks repaired on TTA heads in the past with no problem. Champion does this type of work.

The problem is no water between the valves and it gets very hot.

what about the 7248 ! is from a 3.0l fwd !

7515 is the preffered. But the 7248 will also work.

You can also send them to alltex cylinder heads. You can also find them on evil bay. One guy has them on pretty regularly, brand new and fairly cheap.
