so no one has any?

so GJ scorp head is the easiest way to go? Is that the last of the scorps?

If it has roller rockers does that mean you cant run aftermarket cams?

Is magna head only better because of the roller rockers?

Jet Valves???

what are they on?

the magna head has bigger ports, valves than sigmas and some have roller rockers!
