2004 will be early heads. 2009 I believe is the first year of the Eagle Head.

It's good to see this thread take on a life of it's own!
I've been to busy to flow the other heads and sonic test the 5.7 block. I'm hoping to have some info this week.
Icon just finished scanning the late 5.7 head, and will soon have both a 10.25:1 piston and 13:1 piston with a 3.900 stroke and 4.050 stroke in a 5.7 bore size as well as 6.1 bore size.
This piston can only work with the late head as it's chamber is different than the early 5.7 and 6.1.

Will they offer a stock stroke piston? I have rods in my back and can't climb thru a rollcage. I can only use bars with a swing-out. I'm only wanting to make around 550 hp so I don't need the stroker setup. We talked to Hughes and a few others and the 550 mark will be an eay build with the stock stroke and eagle heads, drag pack intake, good headers and a mild hyd roller cam. I just wish a roller rocker setup wasnt almost 2 grand! Thats just crazy! We will be knocking the block 40 over and needing forged slugs. My magnum motor has been racing for 7 years and went 5 years with the valvecovers never being taken off. I hope the 5.7 will be the same but with more rpms and fun. 
Yes they will offer a nice stock stroke piston but be carefull about using the late 5.7 hemi head with a stock stroke. TQ will be very low at low rpm so if your going to use tall gears for the street, I'd either go with the early 5.7 heads with some slight porting, or the late heads with a 3.900 or 4.050 crank.
Don't use the stock rods!
Sorry I have kept you guys hanging...I just took the family camping for 4 days to get away from work and spend some time with them.

Brian, it will be a basic bracket foot brake motor. I am running a 904 trans with a T/A 8" verter with a 4800 stall, 4.10 rear gear with a 28.5 drag radial. The car weighs in at just under 3300 with me in it soaking wet. Cam motion will prob cut me a camshaft. They said they have a wicked stock-elim grind for it.
76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.

Brian your statement here is because the head is too big?

It's a pretty large port. I'd be willing to bet it'll hurt low speed TQ over the early casting. But with a higher rpm range, and good compression the late head should be much better!

it's gotta be all relative, as my '11 charger R/T doesn't feel like it's soft on the low end, even with 28.6" tires, 2.65 rear and 3.59 1st gear (so, equivalant first gear as a 727 with 3.8 rear gears and a 28" tire, or 3.66's and 27" tire)

Thats because the VCT helps on that. however most guys will lock out the VCT when doing a swap because their is no after support yet for that.

Did all the flow testing today. Now the 6.1 heads I have, someone has done some mild cleanup to the ports...doesn't look like any carbide work just some flashing removal and blending with a cartridge roll.
Other than that, all theads are untouched OOTB.
First is the pre '09 5.7 head with stock 2.00x1.55 valves and factory VJ:
Lift Int. Ex.
100 72 54
200 151 120
300 223 158
400 256 177
500 265 186
600 267 190
700 268 190
Late 5.7 Hemi with 2.03x1.55 factory valves and VJ:
Lift Int. Ex.
100 72 52
200 155 116
300 233 156
400 283 182
500 303 192
600 308 195
700 311 196
6.1 Hemi with factory 2.08x1.6 valves and factory VJ:
Lift Int. Ex.
100 72 61
200 146 122
300 221 170
400 278 200
500 315 205
600 334 209
700 338 210
So what does it all mean? Haaaa....I think any of these heads will work awesome but they do have drasticly different port shapes and sizes. I'll post pics tonite so you can see them next to one another.
I really like the later 5.7 head with the smaller chambers. And they have much longer valves than the other heads have as well.
The early 5.7 had much faster intake ports since the ports are much smaller than the late 5.7 and 6.1 so they should work best with smaller cid engines and lower rpm strokers especially with some mild port work.
I'm hoping we start doing some testing here within a couple of months and anything we do I'll post it up.
