I dont know the difference, but a friend has a set on the 5.0 he just put in his T-bird Turbo coupe,uses their cam and intake and runs 13.1 in that tank ,and is easy in mid 12s with a small squeeze from the bottle.He plans on bigger juice set up in future.This car has everything working pw,pl,and ac,and he drives everywhere in it like Carlisle(sp)or any where theres a drag race.

I think the Track Heat head are just Twisted wedge heads with better valve springs. The "Street Heat" heads are really a more race oriented head with the exhaust port relocated upward about .400 or so.
The "Street heat" heads are also called "High Ports" also.
For the money I think the AFR heads are the best deal. They are CNC ported in various flavors for you different requirements.
Neither Trick Flow head is a monster in it's unported configuration, but the Street heats have won a ton of races ported.....

I have AFR-185 on my 65 when ordering they ask for all info such as intake and exhaust set up and I dont seem to have a problem.They are very nice pieces.

I've got Track Heat heads on my 333. I haven't dynoed the thing yet, but it is frighteningly fast

The Track Heat heads do have stiffer valvesprings, but they also have back-cut stainless valves, thicker deck surfaces and 7/16" rocker studs.

The Trick Flows do have the rotated valves, but that can cause problems unless you flycut your pistons (I did). They require longer pushrods, but you can't just order them out of a catalog... you MUST do a geometry mock-up and determine the length yourself. Head gaskets were another problem. The steam hole pattern in the decks of the heads are Fel-Pro pattern~ I don't think so, not on a high winder at least. I had a custom set built to my specs (read: $$$ ) to accomodate not only my cooling pattern (which requires drilling additional holes in early blocks) but for the assembled quench height I wanted.

These are bridges to be crossed in full-blown race motors of course, sure seemed like an awful lot of work (headaches ) for a thumpin' little streeter.

Don't get me wrong, I'm more than happy with the results the motor makes far more power and torque than I expected it would. Traction is my biggest problem

If I were to do it again, I think I'd try a pair of AFR's

Soon, I hope

I've got far too many projects going at the moment . Realistically, I'm hoping to get some hard numbers by the end of the year

I have the Street Heads on my 65. My combo is probabily a little mild for the heads. Mine are ported. They have run these on cars dipping into the 9s so they can flow plenty. I have no complaints and I am running them on a street car not a racer. When I go to a 408W I was planning on using them again.

The TFS street heats are really the best head out there... They will work on a car from 13 sec. to a 6 sec car..The reason people are lookin for them is because they will work on any combo.. I have a set on my street car.. that runs 11s on the motor.. 306.. Those heads will flow over 330cfm on the intake.. they are killer heads.. If you get a set of those heads u don't have to worry about buying more..

I have heard tales that the "Street Heat" heads are difficult to port properly (unless you know the proper tricks).
Is that true?

my machinist said he does not like ussing twisted wedge head heads on any daily driver becuase of excessive valve guide wear.i went with afr and cosidering they are fully cnc ported you get best bang for buck.i was a little bummed though when i found they ussed two different makes of valves.they had rev cl 9000 ex. and manley r76a for in.these are very inexpesive valves that required different installed height on valve springs.they had stacked so many shims in intake valve pocket there was no pocket left!!!!!i ended up machining valve pockets wider to accept hardened cupped washers.also they ussed pioneer screw in rocker studs (which went right in trash).i understand this is how they keep cost down and have been told by afr that these were first generation and they no longer use manley valves

Personally I run Edelbrock Vic Jrs, I've even met Victor Jr., he's a bit older than me and a great guy! His heads run pretty well too, and they don't have twisted crap or 'D' shaped ports.

The rumor about TFS valve guides wearing out is old news. They revised the the iron guides and geometry years ago to fix the problem very quickly. I bought a used Twisted Wedge set last year for $500 that had 10K racing miles on them and the machine shop said the bronze guides and valve seats were as good as new. The Twisted Wedge valve and pocket placement for the intake is still different from Ford OEM, but allows much better "mid lift flow" at a lower port volume, while maintaining stock entry and exit locations. The Cleveland head was the same way, except Ford went a little overboard and forgot about port velocity.

The Street Heat head was an early version TFS iron head with raised roofs. The stock flow numbers did not match the Alum. Twisted Wedge heads, but they had great potential for massive race porting. They should not be confused with the Alum. Twisted Wedge heads.

The Track Heat head is just a new Twisted Wedge alum. head with upgraded components for high rpm use.
