If you’re leaning towards the Stealths because of the cost that’s fine....... but you’re kidding yourself if you think they’re the best flowing of that variety of head.

They’ll still be a nice step up from untouched 452’s.
If those are what your budget allows....... just get ‘em. Lots of people have...... and are happy with them.

On my bench an ootb Stealth is usually in the mid-250’s intake/mid-170’s exhaust @.500 lift.

Ootb(zero porting) Sidewinders/Speedmasters are basically the same.

346/902/452 heads with 2.14/1.81 valves, with a good valve job and the bowls & pinch done by someone who knows what they’re doing..... also basically the same.


Not the money, its the chart you posted in an old thread I found, it showed the stealths were second best flowing after the trick flows and the e-street dead last in flow..I will look for that thread again and post it back here.
