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.
Brian
Just got my set flowed 5.7 stock head
intake ............. exhaust
.100 72.2 ............ 56.6
.200 150.4 ............ 112.4
.300 217.3 ............ 148.9
.400 272.5 ............ 176.3
.500 299.2 ............ 183.6
.600 302 ............ 185
not bad for a STOCK HEAD. Matt
I don't think I remember to put the putty on.

I used a 2" pipe on all the exhaust ports when I flowed them.
Without a flow radius on the intake, the air shears at the opening and skews the results.

On the car or off the car?
C CLAMP. off the car. I know about all the different types.
Just thought my simple manual C Clamp type would work better.
Maybe its me but never had a problem with regular heads.
Eventually I will make one that site on the heads and you scew the spring to compress it.

Which block did you get . Same place as the heads?
Will be keeping an eye on you. Lol  
The block i got through jegs. Since the block and heads are going to sit for at least a year while i gather funds to finsh the build.  Since i tapped out my car fund between the hemi parts and Vet's bills
4500 cost for the block
1300 for the heads
2000 for the Vet bills  b/c my 5 pound dog ate Chocolate so there goes the rotating assemble money

No port volumes as of yet. Ahhhh a 6.4 deal would be very nice. I would love to work with the aluminum block too.
I'm so buried here at work who know's when I'll have time to get to the Hemi builds. I'm having some difficulty keeping up.
On a different note...I hope to be building a stroker 6.1 for my Duster by the end of the year so let's keep this going!!

Nice had a 145 lbs rotty that ate a big green caterpillar.
Stupid thing almost died. $$$$$$$
What block did you get? I think the one that is bored to 4.114 is the better one because if the amount of rebuilds you can get. 
Thx for the info.

Brian I think their is only 3 ways to make the Apache head work.
Force induction, spinning.it to the moon in small CID form or large cubes.
The second one I'm concern about possible oiling issues.
The last ,and this is my avenues, is using the 4.25 crank. Apparently BES had to sink the valve .070 to make this work. 
I could be totally wrong in saying this so don't take it personal. I don't think you need any expertise to port this heads.
The port is a straight shot at the valve. No short turn to worry about.
