I wasn't going to argue with the guy, and don't per say agree with his results, this is why I brought the post over to this thread. The head porters here, I was sure had some input on what that post and the guys numbers were said to represent.

I have tested many stock Stealth ports and until recently the best they ever flowed OOTB was 268 cfm. The last three sets of heads have come hand blended in the bowls whereas they never have been before. This is what I attribute the OOTB increase in flows to. On a Stealth port tested last night the flows were. Lift.......Int/Exh .100.........77/68 .200.......157/143 .300.......222/189 .400.......268/231 .500.......302/262 .600.......329/283 .700.......343/293 .750.......346/299 We have a junk Stealth port that flows 350 cfm @ .700" and 356 cfm @ .750" but gives up 6 cfm average through the 8 lifts. I bought a pair of Super Stealth heads, just to test, because I had never seen any flow figures for them. Those are my flow test figures on BIGBLOCKDART.COM Last edited by heyoldguy; 03/03/13 12:16 AM.

Frame of reference? Whatever you're comfortable with, I guess. What do you charge for that head at that flow would be my 1st choice, so it can be factored against buying a different head. If it takes 5hrs per port, a bunch of welding and epoxy, so you're looking at $2k labor right off then it just makes more sense to go Victors or B-1's from the beginning. I mean for racing, it makes sense to do that anyways but the vast majority of mopar guys seem to want to squeeze a turnip for blood BTW, thanks for posting, it seems that a lot of folks want to attack you, for whatever reason, and I appreciate that you keep going.

The last set of numbers you posted are obviously a ported set of stealths , CORRECT ?? And are they Stealth or Super Stealth ? Still waiting to see a comparison of your work on another bench for a reference Correct, the flows in the above post are a ported set of standard Stealth. Here are 325cc CNC 440-1 and SUPER Stealth flows from our bench, (1) column is OOTB Indy CNC 325cc 440-1 (avg of 4 ports), (2) is OOTB SUPER Stealth, (3) is ported SUPER Stealth with a very lazy attempt at porting the exhaust. The exhaust port in the Super Stealth, in my opinion, is inferior to the standard Stealth. Lift...........(1).............(2)..............(3) .100........66/61.........72/61..........75/65 .200......141/114......147/124.......155/139 .300......212/163......208/161.......218/184 .400......267/207......250/190.......268/216 .500......309/241......276/207.......313/240 .600......347/267......280/217.......344/259 .700......360/285......280/224.......354/275
