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)

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.

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

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

i sure would like to wait and probably should but i allready paid for a sett and there porting them right now i should have done a little more investigating work i guess i could have put on my sett of ported pi heads with 1ml. larger valves 600 lift springs but i got excited when heard about the heads and to have a sett for my new build.

thanks i will have to read it i will try to get down to the shop today to snap a picture of that intake.

i just read the artical it seems ron spoke the truth on the numbers i dont if it would make any diff but ron does cnc porting mmr does all hand work i know cnc porting makes for more even numbers thu out all ports but i wounder if you hand port you are able to get better flow 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.

so do you think it might be possible for mmr to hand port the trick flow heads and get that much more power out of them than rons cnc port at fox lake?

hey whats your take on intakes? did alot of research and still dont know if i made the right choice! i think the p51 is probable the best overall intake out there i almost went with logan but it is to tall with a 5.4.I think i would need a 5 inch cowl hood. The new trick flow had some pretty good numbers but think its going to suffer extreme heat saturation and loss of horse power. I already know typhon is a piece of crap, and dont get enough rpm out of stock plastic. I went with a edlebrock sullivan elbow and cobra twin 64 throtle body it will suffer at low rpm but im hopeing i can take advantage of it at 5500 to 7000.what is your take?
