If they are ported? Hell yes. The OP didn't specify though - I'm assuming he meant out of the box since porting on top of the castings is a lot more cash then the AI TFS heads and would not be an even comparison - plus most builds will not need that much head. AI TFS packages are a great deal when looking for a proven performing group of parts and not picking different parts of the car individually.
You can have them converted for a relatively small fee. AFR 235s are one of the baddest 23* smallblock heads on the planet. We are talking over 340cfms...the "big boy" forums(the ones with more racers then ricers) love 'em
.
They are huge though, so you better cam them right to see much benefit over other heads...they would be a waste on of these baby 24x hyd roller cams with .6" lift.

which ones do you prefer? AI 215TFS
why do you prefer them? I'm running them on mine and making an immense amount of power with great results
What engine, drivetrain combo do you have?
385c.i. 13.9:1 CR AI TFS 215cnc......AI SR Cam
little bit of extra lift 
AI Ported Victor E Single Plane
4L60E 5000 Vigilante
4.56's Dana S60 w/28" Slick
what intake are you running, stock, sheetmetal, carb?
AI Ported Victor E EFI/ Wilson Elbow Wilson 105mm Monoblade
What made you choose one over the other?
AI's port efficency and chamber efficency as well as the overall technical vibe i got from speaking with them....they KNOW their stuff!!
Are they stock or ported more?
Read above
See Sig for more info and times........yes the car is an ALL MOTOR NATURALLY ASPIRATED car i drive on the street

Just checking the thread and noone really has these heads huh? I cant believe noone has these heads. I thought more racers had these bad *** heads.
Can either of these heads really benefit from just a Hyd Roller cam? Or is a SR really recommended to maximize the power benefits?

Our setup are very similar, with the exception that you FI and I'm carbed. I just installed a new custom grind SR cam and the 456 gears and ran the times in my sig. I should be in the 9.90's in the 1/4 the next time I get to a 1/4 mile track, but I'm also about 200 lbs lighter than you are. Good luck, you should be in the 9's soon.

That's sweet you can drive it on the street, I gave that up along time ago, and your right a PG and a 8in converter would set yours on fire. Hell, if I had a 8in converter instead of my 9.5in I'd be quicker and probably mph 108 or more in the 1/8.

It is interesting that some feel they need more potential than our 215cc TFS head when the overwhelming majority don't build engines that will run our 200cc CNC'd GM casting to potential, much less our TFS casting based heads. That isn't intended as a slight against anyone, but most balk when we tell them they need to build the engine around the top-end, which can require a different piston/header/etc. to run best. We do have higher capacity port arrangements in other castings, but we haven't ever invested the $ in producing them for the LT based crowd due to lack of demand.
If you guys truly feel you want an LT option with more potential than what we currently have, then we're more than happy to produce it if a few will step up and commit.

When you start talking monster heads like ported AFRs or converted SBC race heads, you could easily slow your car down if you are running a baby cam like that without the gearing/stall/transmisison to support it. You're not going to be doing much street miles anymore though when your nice peppy street car now has a 25x cam, 4400 stall, and 4.30 gears. Just like with cams though, its hard to convince people that bigger isn't always better.
It is not cost productive to invest in those kind of heads for the small amount of people who do not care about streetability or whose cars are weekend toys or trailer queens. There are only so many Sikoras, Shepards, and Jakes :p
