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.
