Opinions? Yes. Facts yet? No. The Super Stealth will probably have it's niche and may outflow the Stealths. How much? Right out of the box it should if they have improved the bowl, max porting to max porting, not much I'd wager. It will be fun to test.
There is a reason the high performance heads use the longer valves that the Super Stealth does not have. The S/Stealth will never ultimately flow with the Indy's or Victors simply due to the port height you can get with the longer valve. The main bottleneck to port flow has NOT been the pushrod pinch that the S/Stealths have removed, but the shape of the port under the valve, the short turn and the depth of the bowl. It's an over simplification I know, but still the truth.
It will be very interesting to see what gains you have made with the porting on the Stealths. Be sure to let us know.
Has anyone seen or used the new 440 source super stealth?

Any opinions?
I have ported my stealth's till they hit the pushrods. check out my pics
Just waiting for it to stop raining so I can see the improvement at the track.
Stock stealth's gave me a 11.4@118mph in a 383 stroked to 496
I'll let you know how I go.
