Comparison of Trick Flow 220 As-Cast and 215 heads please

Thought I would post this up as some might be interested. I picked up a new set of AS cast Trick Flow LS1 heads. I had them milled to 57.5cc and had them hand ported and flowed by Tooley at TEA. Intake runners weren't touched. Only work done was on the chambers, and a mild port to the exhaust side. The price for the heads and port work comes in much lower than the LS1 cnc heads. Here are the numbers:
Lift int exh
0.1 71.7 59.5
0.2 137.5 110.9
0.3 214.7 167.3
0.4 269.6 212.1
0.5 303.5 239.6
0.55 314.2 247.5
0.6 321.7 252.4

Wow....our intake cfm is about the close, but your exhaust is way up. If you mind me asking how much did you pay. It was 250 to have mine touched up. I looked at my flow sheet. I had the same operator, and mine were done on 3/16/2010.... crazy!

TEA actually has two benches that they flow their heads on. They have a flowdata and a superflow bench:
Your exhaust number seem really high. 322cfm of exhaust flow is a lot at .600 .
These numbers are more along line of what TEA advertises on their site for their 215cnc ed heads. I am looking into picking up a set of the as cast 220s for my stock L92 bottom end. Picking which heads I want to run has been the hardest part so far. For the price these seem like a really good option for what I am looking to do.

The bottom line is a flow bench is a measuring tool, and we feel the Flowdata is superior to the Superflow simply because the heads that flow best on the Flowdata, make the most power on the dyno, and seem to run fastest at the track. The Flowdata flow bench uses a Meriam Instruments laminar flow element to measure airflow. A Superflow uses an edge orifice plate, which is a very crude way of measuring airflow. Meriam is the world leader in gas flow measuring, they will tell you the only way to get close to accurate results with an edge orifice airflow measuring device is to have 10 diameters of piping before the plate and 4 diameters of piping after the plate. So if you are flowing a 4” bore head you would need 40” of piping before the orifice plate and 16” of piping after the orifice plate, the Superflow has NO piping before or after the orifice plate. Some of our competition in the Ford world used to bash us on flow numbers, but then would turn around and say “but the stuff does make power” so the bottom line is if it makes power, then who cares what it flows on a crude flowbench?

I contacted brian tooley directly here on the forums. The heads and the porting were sourced through tick performance. I'm sure you could get the same setup through any of the vendors here also.

Bringing this back up from the dead:
I'm in the middle of choosing between the 220's and 215s for a street car, and was hoping for some more comments: I was almost dead-set on the 215's, but Brian has been kind enough to recommend the 220's with his hand touch ups.
It all almost sounds too good to be true: equal power at a significant cost savings!
Does anybody else care to comment on the 220s vs the 215s? Does the lack of CNC porting have any affect in the long term? (For some reason, I have it in my head that the As-Cast intake and exhaust ports would collect "gunk" as opposed to a CNC machined one….. I know, stupid thought, but all I can picture is a 3" PVC sewer pipe vs a 3" PVC sewer pipe that had sandpaper run through it)

I have had my TFS/TEA 215s for 3-4 years now. I had them on the stock 346 and with a cam and intake put down 462hp. I then stepped up to the motor now (402) and had the chamber opened up to 4" and put down 530hp at the wheels. They seem to work quite well on either application. I think they were worth the money. Attached is the original flow sheet.
