More ported L92 head pics
Hate to bring this one back from the dead but I am willing to bet these heads dont flow that well,if they did,youd make a hell of alot more than 710 to the wheels.....
Anyone can fudge flow #'s and I am willing to pay shipping to and from a reputable head porter to show you they dont flow near 300cfm at .400

Not sure where you get off telling someone their heads don't flow what they say?? I read your post about your heads and what makes you think yours flow what they do?? Did you look at the pictures of the port work? His have ALOT of material removed from his and they are flowing just a little more air then yours (according to both of your flow numbers) His heads have to be the most heavily ported LS3/L92 heads I have seen yet. He himself says how much they cost to get them to that level, about the cost of a set of AFR's. Now all that said just cuz they flow that well doesn't mean they will make more hp then yours. Not trying to start any ****, BUT you are calling the guy a liar for no other reason then his numbers are higher then yours.
Go to an aftermarket l92 type head or do some welding on the stockers and I dont doubt you could flow 400cfm.....

His #'s are impossible to get,read my post,the casting is too thin to get 30 more cfm out of them without some welding.If you saw a set of max ported l92's in person,you would know what I am talking about.....

most of the gains from "porting" are from the VJ and about 1/2 an inch or so below that,including the all important SSR...so what part of the casting is too thin to get more CFM without welding,in your opinion? what part of the port do you think is the biggest restriction to airflow?
the CSA of an untouched L92 intake port is certainly there to support big flow #s..if the right person does the work,his numbers are totally believable...
You know thats a stupid question. My cam is .720 lift. We took it all the way to 1" on the bench to see when it would stop picking up CFM. Never did "hit a wall" so it seems like a pretty good port to me.
Please show me a NA ls motor that makes 710 to the wheels!! This pump gas motor made 750 at the flywheel. If it makes 620 at the wheels ans runs 9's on motor im sure it will be enough to take out ANYTHING with your TEA heads. Furthermore, its going to take about 100X what shipping costs to get these heads in your hands. Im sorry I didnt buy into the "cookie cutter" mentality as you did.

Intake Valve was a custom 2.150 valve and the exhaust was a custom 1.60.
This is what mine flowed on a 4.067 bore. My exhaust port flowed very well.
Chris Frank at RayMac in FtWorth, Tx did the port work. Could have gotten better numbers but we wanted more thickness for the springs im using.
Motor made 710 before it foated valves. T&D is fixing the problem and we expect another 25-30 out of it at least.

I'm really interested in the head with the porting
Do you they have a web page or contact address...
Thanks...
