Edelbrock stepped header users- any dyno results? Questions...

I have the headers on my car now. The clearence problem was easily resolved by removing the peice right above the oil filter that I guess a oil cooler would hook to. The headers have a lot of clearence and with my motor mounts being in good shape , they slipped right in with stock k member. Remember to put the oil cooler peice back on after install though.
As for power, I gained 5hp and 5lbs of tq on motor over the Macs. That says a lot for Macs too, however though that is at peak. The macs would suit a mild mannerd street car better because of where the tq curve is. Not by much but the macs are alittle better to 4200 rpms or so. (at 2800 the Edelbrocks had 20ft lbs on the macs but at 3800 the Mac had 10ft lbs on the Edelbrocks) Above 4200 they are about the same to 5200 or so where the macs start loosing tq and the Edelbrocks keep pulling.
For the street with my 4.30 gears in a 6spd car, The Edelbrocks lost no streetabilaty as Tq is still not a problem making 370ft lbs at 2800 rpms but up top where I race at, The edelbrocks woke the car up for racing. I have not gotton a good run at the track since tuning but this bastard will fry the tires on concrete with 315x35x17 Nittos from a roll in first and second gear.
Now , for you nitrous lovers. On a 75 shot of nitrous (dry kit with a single nossle under my air lid and a .042 jet) I gained 93 hp and 125 ft lbs of tq to 518/535 to the wheels
I want to comment also on the fit of the y pipe also. It fit great and is a beautifull peice of work. the y is not a flowmaster style but the best welded in one that I have seen yet. this kit comes with every thing you need to put the headers on. It came with o2 extensions , 4 bungs to put all o2 's in if desired , fittings to put A I R back on as well as EGR . All band clamps and even extra extensions to run Open headers instead of using the y pipe.
Best quality headers on the market for under $ 500 with a ypipe IMO. THe Ti Tech coating is really nice looking. I had Mac Ceramic coated headers on the car so It was hard to decide to get Unceramic coated headers to replace them, but these look very nice and are actually the same color as the heads.
THe sound of the exh. is great compared to the macs also, so if the car is no quicker at the track then I wont be upset with the purchase as teh sound is unbelievable . You can hear clips in the thread That SOuth FL posted a link to earlier from the Dyno section.

He welded them to the collectors as per Futral's recommendation. (I'm just quoting AINT SKEERED's response from another thread as I had asked him the same question).

I will put them above the Flowtechs but under the Edelbrocks (even know I didn't get to use them). Fitment was great and I have made great track times with these in addition to my other mods, but just 2 months after they were installed (coated) they started to rust on the passenger side collector. I expected them to show some wear in TIME, not two months. If I was in the market right now (seriously thinking) there is only one that I would get. The new QTP HVMC at the awsome price. Its a proven header over others (SouthFL.02.SS is prof) and I haven never heard one bad thing about them. Some things are just better to pay a little more up front for and be happy, then trying to save a few hundred and kick yourself in the *** later. I have learned the hard way. JMO
