I understand how marketing works, i was just stating a small point, no doubt a set of tfs/afr 215s will out perform any budget head for sure.
what do you guys thing the price will be? same?

Im curious as well, looking at next year. Flip flopping between H/C and SC. Thinkin back to H/C again due to $$. Although everyone saying about the aftermarket rockers for the TFS heads. Don't any aftermarket heads with bronze guides HAVE TO run aftermarket rockers anyway?? Including the AFR's.

this is correct.....the tfs heads don't need rockers just because they are "tfs heads." it’s because the bronze is a softer metal than oem guides....the roller tip rockers are meant to reduce deflection of the valves against the guides.

All this speculation, wheres Tony at to shed a little light? Cmon Tony, throw us a bone over here. Everyone is excited about your new heads. How much longer before that Indy bound Motor is done being tested ?? Can't wait see how the afr 215s did on it.

You guys should rethink the way you compare heads and quit just comparing flow numbers. There are quite a few other "parameters" that could make head X flowing 320@.600 much better than head Y flowing 320@.600
Just comparing flow numbers is about as lame as comparing peak dyno #s to judge cams; PURE MARKETING.

so ... what would be a better comparrison? flow at lifts under 600 lift or the lower angel of teh tfs valves?
to me 225cc afr instead of 205cc afr or 215cc and bigger cams that peak more and higher in number and rpm .... call me air head but 3000-+6300 rpm where the race is I don`t want better torurqe *curve* compared to more tourqe and hp to drive from a stop at a traffic light in street traffic lol

Of course you want a better trq curve, trq is what gets you moving (acceleration).
But your reasoning is understandable since Kuwaitis like roll racing untill your motor explodes

According to the results of air flow for TFS & AFR 205's heads
i Guessed the results
To see how they were to guess
AFR 215--------TFS 215 - delta flow----delta flow ------flow afr 205 -tfs 205 --- intake
147-------------- 142 +5 -------------( 5 +) --------- 140- 135 ----------- 200
212-------------- 215 - 3------------- ( - 3 )-----------200 - 203------------- 300
263---------------269 - 6 ------------- (- 6 )----------251 - 257-------------- 400
300--------------- 305 -5---------------(- 5 ) --------- 281 - 286----------------500
319--------------- 320 -1--------------- (- 1 )-------- 298 - 299----------------600

First of all marketing BS for almost all LS6 heads....
Only two LS6 heads are heads and shoulders above the rest from what I have seen....Cartek and T4P heads can make the track #'ers to back **** up...... No other LS6 head is close that I am aware of....
Yea I have seen big Dyno #'s but on the track these two will shine. In all fairness I have only seen one set of T4P's but they ran high 10's on what I belive was a low 230's cam.
