[DeTomaso] Valley end wall gaps-revisited

[Larry Finch]

Despite what their representative told me, that the ports are not raised and the heads are no wider, the issue causing the large valley end gaps is related to something about the design of the CHI aluminum heads. 

Using the same iron block and iron heads, I dry fitted my old performer manifold and the new blue thunder manifold.

The gaps with both of those manifolds are essentially the same.

Tomorrow I will be taking an iron head to my engine builder and we will try to determine what CHI has changed on their head dimensions. 

Stay tuned. ;-)
