The Jatok manifolds are all that I have ever used. They are on my car, since
1966, on the ex Lew Spencer Super Sport, Baby Doll V, and I have installed
them on all of the conversions that I have done. They work great! With 45
DCOEs we have seen nearly 190 hp at 7200 rpm with a standard displacement
engine with standard valve sizes. We had a 306 degree cam, 13.5:1 CR and
Carrillo rods. A very good head and tuned headers were an essential part of
the package.
The casting boxes are still around, and a new run of manifolds is being
considered.
