Saw them, touched them. I was going to post, but I haven't had time to do much since we got back from Vegas. I have the flow figures and have spoken with them about becoming a dealer. I'll post the figures when I get a chance, maybe tomorrow. They are on a business card in a big pile of catalogs somewhere. Of course, I did not have the camera with me when I looked at them - or when I spoke with Jack Roush later.
They are a 190cc intake port, 2V size with meat to be hogged out to 4V size. The exhaust is raised .100 and has a nice "D" shape to it. I forget the valve sizes but I think they are 4V or there abouts. Springs are good to about .680 lift. Chamber size is 62cc. Should sell comparable to the Edelbrocks, in the $1900~2000/pair range. Flow figs look decent and the head is very, very nice in person. No word on availability but should be soon.
190cc "as cast" finish intake port volume.
62cc CNC profiled heart shaped combustion chamber.
2bbl port opening (has enough meat to port match to a 4bbl port).
Flows 300 cfm intake / 230 cfm exhaust @ .600" lift right out of the box with no porting.
Stock valve locations/angles are maintained so piston usage is not an issue.
Roof of exhaust port is raised .100", the floor of the port is filled in to remove the dogleg shape of the port. Header fitment is not affected.
Initially we will be offering a 1.460" dual spring (120lbs seat / 390lbs open) that is good for .650" lift & a 1.530" dual spring (138lbs / 430lbs open) that is good for .680" lift. Additional spring options to follow.
7/16" ARP screw in studs / pushrod guideplates.
I also don't think my current business model qualifies for their dealer program, but I might know someone that does. That person also owns a dyno and a plan would be to join the dealer program, get a set and do a back-to-back test on the dyno. The engine in the Mustang is a "typical" 2V - home ported heads, flat top pistons, etc. I'd like to put an F-238 solid in the motor first. I have an Excellerator and the 2V Funnelweb that's on the engine now. A dyno plan would be to run with both intakes on the iron heads, then switch to the TF heads out of the box and run two more tests. If it would pull together, it'd be 4-6 months from now because the dyno shop is under construction. There's also the question if the owner wants to even market TF heads. I would personally like to do it, do a write up and shop it to the magazines.
Update - these are supposedly with the 190 cc port, 2.08/1.6 valves
The 2V we have uses a 226/230 hydro right now with ported open chamber 2V heads. In good air, the engine makes right around 400HP, 300~320 RWHP based on weight and MPH on the track.
I'd estimate that using even the old school F-238 and the new TF heads would net a bump of somewhere around 60 ~ 80 FWHP. With one of the newer Lunati grinds in the 240+ intake range with 106~108 LC, closer to the 100 mark. Yes, that would knock a couple of folks back on their seats.
Two hold ups here - 1) friend is not set up for business yet and 2) I'm fixing to start about a 3 month chop/cut/rebuild of a kitchen & bedroom that can have no delays if financing and delivery schedules are to be met. And it ain't like TV - floors, walls and ceiling have to come out to the studs and go back. Ugh. Where's Ty Pennington when you need him. BUT - If I get the house finished, then I can finish the shop and I can devote most of my time to car things. I just bought a new framing nailer, so I get tools out of the deal and she gets a decent kitchen. Boys and girls gotta eat.
Good to see another player come out with C heads.... the more the better.
Whilst flow numbers don't always indicate performance, they are very close to CHI's 2V's but as mentioned...with smaller valves. That should mean they are potentially better.... time will tell.
Keep em coming manufacturers !!!

TFS has 351W specific upper and lowers so they do have an upper with a large enough plenum volume to handle 351ci.
I've been keeping up with Tod's block but I'm hoping for something I don't have to find a specialty machine shop to finish machining before assembly. Decking, boring, and honing are all I trust any of the local guys to accomplish on a Ford motor....everyone speaks Chebby around here but a few have expressed some interest in my "big block".
