X heads on a 360?

-
The problem with your logic is, he already has 2.02's in the X head and doesn't have to spend a dime to upgrade the other heads which are inferior at present. Not all heads port out the same. While the early castings can be ported well, I have not seen them go as well as the XJOU.... heads. I know that doesn't mean someone can do that work......

The 2.02 can indeed make 20+ HP over a 1.88. No question. Seen more power differences between the two. HOWEVER! It is also the combo tested that shows a big or small one. Even mild builds have a good spread.

At this point, I can't see selling the X head to roll the sale cash into a smog head that starts with getting rid of 1.88 in favor of a 2.02. IMO, that is just insanity.
I agreed with you I would just sell them and get aluminum heads.
 
The x heads would be pretty valuable to a resto guy who wanted to run the correct head with the porting being a bonus, but do you really need more head than that for you combination? So selling them to build a better head could be overkill.
