If I'm reading the rulebook right any head run in SS/CS must be NHRA accepted. The list of approved heads on nhraracer.com doesn't include any Ford heads for SS/CS. What am I missing?
"All heads must be NHRA-accepted, two valves per cylinder, except in classes DS, ES, FS, and GS, four valves per cylinder permitted." |

As a Ford competitor, you can run any Ford manufactured factory cast iron heads. They must be accepted if they are an aftermarket casting (Dart, Brodix, etc...).

Thanks Mike, I always thought that was the case, but the wording above (2017 rulebook) threw me off.

Ford makes a head that fits the SS/CS spec of "Inline iron" called the N351. It is primarily for short track circle track racing. I did a lot of digging on this head and found it on the 1/8 mile record holding Mustang of Venice Perno.
It has a Ford part number, M-6049 N351, so it's not technically "aftermarket". Got mine from Speedway Motors. Require offset rockers and special headers. links: http://dragracecanada.com/ontario-ford-aficionado/ .

Here's some pics of N heads on a BOSS302 block in my 68 coupe. It's a work in progress running in Pro at the moment. I just rebuilt the front suspension and will get it out for competition this weekend.

Ford Performance has discontinued the N351 head and Speedway seems to be the only source of new ones. They must have purchased a bunch of them.
