Do you believe porting numbers
#11
December they stated ready for March, when if like the last heads we will see them summertime. Honestly I would wait myself if you can, the R head is really nice and you can't match its ports with the standard TFS casting without making a window (which I have done myself)

@ .500" lift:
intake - 259 cfm
exhaust - 189 cfm
@ .600" lift:
intake - 269 cfm
exhaust - 195 cfm

just found it.. it's in the March 2010 issue of Muscle Mustangs & Fast Fords. page 53. the guys doing the build had Fox Lake port the Trick Flow heads, and then sent them to another shop to get independent flow-bench numbers.

For all out race a CNC followed by a hand polish is the best way to go, I have never seen a CNC match up 100% when the cutter meets from the gasket side to the valve seat side. However doing both is more expensive obviously.
It depends on the head whether or not a CNC only is better than a hand port only. The more material you have to take out and/or the smaller the access the better the CNC is. I can get 210-220CFM 2-3X faster hand porting a PI intake port than a CNC can. However LSx intake ports need a CNC, they are about 2X faster than hand porting that head.

have you heard when? i hope they dont have nearly the problems of the last castings those have taken forever they have recently switched foundries witch has even put them further behind. trick flow told me for every 100 castings they turn back 80 and assemble 20.
