Do these fit stock SC heads and valves?

To the best of my knowledge the SC heads are dimensionally the same as Mustang heads and would, therefore, work just the same. Maybe someone could answer this question in the tech section.

No, they do not fit a stock SC head for several reasons, the first being that the SC has 11/32 valves whereas the later Mustang 3.8 (and all 4.6) motors have 7mm valves. There are other reasons as well. They can be used with aftermarket valves and hardware.

Thanks for clearing this up. Much appreciated.

you might try advertising these on a grand prix forum.. These are popular springs for the 3800 v6 as well. These are a drop in upgrade for those cars when LS1 retainers are used..

These springs can also be used on 1996+ v6 mustang heads with Ford 4.6L 2valve v8 retainers.

Hope this helps, and free ~BUMP~
