There are two versions of the 915 head, the GTX got the 915 HP head which has a larger exhaust valve . If you are having problems finding 915 heads , Mopar also used them on the marine version of the 426 wedge in 1968.

You canput 1/75 Valve in the 1.60 Head.
You are not going to run stock valves anyway.

The 1.60 head fit more applications that are run in stock
currently.

The 1.75 Heads have HP stamped on the front flat surface.
