Dont know if i could swing the TF's..I was reading some old thread where you posted flow numbers and the E-street was dead last, so that kind of bums be out on the edelbrocks..What needs to be done to the stealths to make them trustable and reliable?

I'm a little confused. What exactly is your goal? Sounds like the criteria is the highest flowing head. Consider starting with a goal for the car. What does it run now? What do you want it to run, and what is your budget? You cannot pick the appropriate head flow/$ in a vacuum of everything else. Here is the way it generally works: the more you spend on the heads, the more they will flow.

Depending on your current performance/power, any more flow above what the Eddys have might simply be diminishing returns.

Best deal I got was with Marsh sidewinder's..I had my RB 906 heads with mild pocket porting ,swapped them for otb sidewinders ....The motor was tuned as best it would run..11.8... I bolted on the Sidwinders with no change in tuning and picked up 2 tenths.. after dialing in got 11.3..

Between the Ede, Sidewinder, ProMaxx, Speedmaster, Stealth heads...... ootb..... the Stealths flow the least.

I didn't realize how much more the TF's were than the eddies and stealths until I got to looking last night. The e-streets and stealths aren't too far apart in price and THATS the price range I will be looking at, unless I were to stumble upon some used TF's at a deal. I just cant swing the money for the TF's due to having family to care for and all. So I guess I should say, with an eddie/stealth budget, what would be the best flowing..but after reading Dwaynes chart on another post, it looks like the stealths, but im not the expert so I will keep listening here.and I know there are other heads in that price range too. Also, what are the 'super stealths'? I did not see these on the 440 source website...remember also, I am willing to change the cam for a better one too.

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.

Has anybody asked the OP what sort of $ he's willing to put out for a cylinder head upgrade? I've always found the money factor to be a good reality check against expectations... even if I've chosen to ignore it.

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.

Sorry fast, you didnt post it, i got screwed up with my names with all the reading im doing, but here is the post and its close to the bottom
https://board.moparts.org/ubbthreads/ubbthreads.php/ubb/showflat/Number/2057285/Searchpage/4/Main/175727/Words/%2BE-STREET/Search/true/re-trick-flow-vs-stealth-vs-super-stealth-for-505-build.html#Post2057285

Here are some numbers that fast68plymouth has posted. I've restricted the numbers to intake flows up to .500". All tests were done on the same bench, bore and pressure drop.
------ TF240-- Stealth-- MCH Stealth-- BOX RPM-- BOX E-street
.100"- 71.6- - - 65-------- 70----- ------- 67--- -- ----62
.200"- 156-- - 144------- 161------ ---- 141--- -- - -122
.300"- 229-- - 207------- 222---- ------ 209 - - ---- 183
.400"- 274.8 - 238------- 263---- ------ 245- ------ 230
.500"- 302.9 - 247------- 289---- ------ 267 - - -- - 262

From that thread:



It’s important to note the E street numbers listed there are for the 75cc version, not the 84cc version(which flow the same as the 84cc RPM).
The 84cc version has straight plugs.

The 75cc E street has some additional valve shrouding because of how the chamber is pulled in closer to the valves.


With some blending, the flow deficit can be mostly eliminated........ for those combinations where the 75cc chamber is a better fit for the application(but don’t want to give up that mid-lift flow).

Correction my Stupid Stealths [Super Stealths] flow real bad .200 to .500 compared to the TF240's

Hard to say for sure without numbers for both from the same bench.
