Been working on first set of these I've done.... Out of box, W/2.15 Ferrea Comp Plus LIFT---IN .100"--68.7 .200"--147.1 .300"--212.9 .400"--268.6 .450"--286.6 .500"--294.4 .550"--303.6 .600"--312.4 .650"--324.3 .700"--321.6 ICH claims 330 @ .700" in their literature. I did a VJ, and a 10 minute seat/ST blend: LIFT---IN .100"--69.6 .200"--146.8 .300"--210.2 .400"--265.7 .450"--292.0 .500"--310.3 .550"--320.9 .600"--331.9 .650"--331.9 .700"--331.9 I was'nt happy with the shape/size of the ICH short turn so.... another 45 minutes of work....(also opened Pushrod area .100") LIFT---IN .100"--69.6 .200"--143.6 .300"--210.2 .400"--268.9 .450"--294.2 .500"--312.6 .550"--331.2 .600"--343.6 .650"--351.4 .700"--360.8 Misc notes: Actual Min CSA of the out of box port..... 2.85" 245 CC Actual Min CSA of my 360 cfm port......... 2.95" 255CC Intake manifold fitment is a definite concern, as the out of box port window is 2.4" tall. So after port matching the 360-3R ICH manifold you have ~.060" of gasket sealing area above the port. The exhaust port and chamber are basically the same as the 230 CC CNC -2 head.

i find that interesting. here's the flow numbers you provided with a set you did for a customer of mine. they weren't cnc'd ports but these were supposed to be a max port job. i thought it would be worth a look to compare to your new findings.
.100"--82.8/N/A
.200"--157.3/110.4
.300"--217.4/158.0
.400"--262.9/203.6
.450"--286.0/214.6
.500"--304.0/221.9
.550"--318.1/227.1
.600"--322.4/230.5
.650"--332.9/237.4
.700"--334.0/241.2

Yep, that would be about a max effort -1 rectangle port that was hand ported. Those heads start at 210 CC, and in that level of port work are aound 228 CC. There is just no way I would port a set by hand out to 255 CC, I would have to charge $2000+. I'll get some pics today of a 245 CNC sitting next to an unported -1 rectangle, it's absolutely silly how much material has been taken out of the roof of the CNC head. Like I said, the port is so big, the ICH -1 gasket and manifold don't really "fit" anymore. It would be nice if they came out with a raised runner intake for this head. I'll get a pic of that today as well as I worked on the manifold yesterday.
The exhaust, I only flowed one so far, just with a 3 minute sand roll job and it went 256 cfm. I have had the -2 Oval CNC exhausts up in the mid 260's before. So that's about what they can do, 255-265 cfm on average.
Gerig's car should run around 9.10 @ 148 @ 3000 IMO.
I'm going to do a set for Vic Bailey's new 454" "street" engine (guy who owns B3422W5's old duster) 4.125" X 4.185", 13:1 with a roller, and I'm going to angle mill them 2 degrees. (48 degree block) Should be an easy 700 HP combo. It's just nice to have a head that has ALOT of cross section and is still a true 59 degree piece. This is what the big inch SB's have been needing. CSA wise it is bigger than most W7/8 heads other than BIG sprint and Drag heads. Liek a typical Craftsman Truck W8 has 2.78" CSA, my Lemans heads are 2.55"...
They don't cost anymore than any other INDY SB head. The CNC cost is same on the 245 as the 230 -2 Oval etc. This set and Vic's set I am going to mill the pedestals on and we are running ICH/Jesel .800" offset rockers to eliminate the 440-1 junk. In fact 3 of 4 sets here right now are being converted to Jesel and the last set I did a few months ago also were converted, so it looks like guys are finally willing to pay a little more $ and get the good rockers finally. I know the Jesel and T&D stuff is not cheap, but once you use it, you'll never go back to anything else.

230 CC CNC -2 INTAKE PORT, keep in mind, if you've never seen these heads in person, for getting a feel for how big the 245 head is, a normal W2 head fully ported is in the 195 CC range. So the 230 CC Oval ICH is a BIG Oval, and the 245 rectangle dwarfs it. The actual minimum CSA of the 230 CC CNC -2 is 2.52" Someone wanted to know taht a few months ago, and I just got around to measuring it today.

My prediction 9.35@145. Ryan why not use a W8 Intake with this all you have to do is mill it down to fit. Then port and bolt match and then hog out the intake to move the big air.
Career best 8.02 @ 169 at 3050# and 10" tires small block power.
