Okay, after researching alot of posts, I still don't really have a firm conclusion on which heads would be best for my setup which would include a stock 99 ls1 shortblock, full boltons, m6, and a tr 224 224 112 567 567 cam.

With this smaller cam, do the AFR's give up much overall since the lift isn't that high? Or, is there better power/torque all over the curve from either the tfs or the etp's?

The car is a street car and only raced occasionally. Good torque is what I want down low and I won't be shifting much higher than stock. Do the tfs or etp provide the tip in/throttle response that is known of the afr 205's?

If a lot of people see this thread, you may have just started a war.

When not running much lift, one needs to look at the flow in the low and mid-lifts, plus the air-speed of the cylinder head. Honestly, an arguement can be made why each brand you mentioned would be the best. The AFRs would have the edge in air-speed (velocity), the ETPs would have a fatter mid-range lift number while the TFS heads would be very good in general in the mid and upper flow range. Like I said, each head has a compelling reason why each could be considered the best.

Best advise is to choose the one that meets your budget and also allows you enough $ left over to mill to the desired compression ratio. Remember, compression is your friend.

Thanks Patrick. My main question was basically if the ETP 215's and the TFS 215's would have the same excellent street manners, tip in, and throttle response as the AFR 205's have on the bottom end? I know both the 215's will flow great in the upper end, but I don't want to sacrifice any bottom end.

I know all three heads are good but are the AFR's better for a smaller lift cam that is in a car that spends most of its time on the street?

Any of these heads would put a smile on your face....IMO they represent the best of whats currently on the market in a CNC ported cathedral piece with all three featuring quality oozing in their machining and CNC porting work and execution. Pick your favorite flavor when it comes down to HP production....on the same flowbench you won't see big descrepancies in their usable flow numbers. Coupled with the right camshaft and other complimenting components all three will make serious power.

That said, I feel the AFR's slightly smaller intake port will have a slight advantage in what your looking for which is tip in and throttle response (all part throttle activities if you will) and that is something a dyno will never measure that I try to bring up from time to time that a lot of potential customers seem to overlook. Also, the AFR's are a true factory replacement bolt on design that is emissions legal with a CARB number attached. Another few perks for those that care.

Add what I feel to be excellent customer service and support in general and what's there not to like as a potential buyer.

Nothing but good choices here and when you remove the cheerleader factor (guys hopping on here thumping their chests about their favorite brand), your simply left with three top shelf high quality CNC piece that can all get the job done. Trying to choose between them has to start trickling down to other smaller decisions and features that may sway you one way or another.

If your considering our product and have some additional questions, feel free to contact me personally when I return from the PRI show next week...

Cheers,
Tony

The above post is exactly what has me leaning towards AFR "small bore" 225's or hand finished 205's for my all out 346 if I don't go the Procharger route this winter. From what I have been reading Tony is always there when someone has a question about his product. Not a cheerleader or anything just stating what I have witnessed as I am torn btw Trickflow 215's and the above mentioned myself.

what are the price differences between the 3?

Thanks for your excellent reply Tony. Where I am located no one has any of these heads so there is no chance of me getting real world comparisons at all. I guess my choice will come down to price and availability because all three heads sound so close, although I do like the smaller runner of the AFR 205.

also, one thing to take into consideration, which I didn't know anything about is knowing what compression ratio your are targeting. Sometimes based on head design, you may not be able to mill down as much as want to and still have good PTV pending on cam used when shooting for the higher 11:1-11.5:1 and keep good air flow.

I've never dealt with any of the staff at ETP. I have had conversations whether on the internet, or by phone, with both Tony(AFR) and Brian(TFS). If you did some searching, you will see that Tony always replies with a good attitude, even if it doesn't have his product being the absolute best all around. Brian, on the other hand, likes to stir the pot. I've seen numerous instances where he starts **** when he could have kept his mouth shut (an example would be in my results thread when I bought AFRs).

I agree with Tony in the AFRs tip in and throttle response. I run them milled with a mild cam (228/230) and couldn't be happier.

To sum it all up, when you have 3 nice pieces to choose from, I would go with the company that has a very stand up individual representing their product, and IMHO, that would be AFR, and Tony Mamo.

Good luck!

Just bought a set of used AFR 205's. Can't wait to get them on the car. My vote is for AFR. Tony is always on here and is always willing to help you out with whatever questions you may have. To me, that goes a long way.

Just curious but why are you comparing the AFR 205 to these heads when there are AFR 215's available?

Philip.... you must not have checked the date when this thread was started

Wow.

9secondsflat

just buy the tfs 215 and y/t ultralights...tfs produce massive torque, make massive peak power and massive power through out the whole power curve from 1500rpms - 7000+

but that is must my .02....you might say i am biased since my little tfs 215 topped 383 made 610 hp...532/472 at the rear.
