I use TFS heads mate & can tell you from experience they fit stock height extractors..
IE the High Port jobbies need adapter plates.
So Genies, Pacemakers etc all fit NO DRAMAS... Which brand are you looking at fitting
FORD.... "POWER TO THE PEOPLE"...
Sorry just one more thing.. If you can spare it get them polished, mainly abit of bowl work & short turn area. You'll be much happier, I know i was after i removed them & had it done..
What exactly is involved with this procedure? How much does it cost? I will be fitting the heads most likely myself so I'll do what ever is needed to do BEFORE installing them. Was getting them polished really a necessity? It obviously was pretty important to you if you removed the heads just to do it.
Ohh by the way I am looking at getting the whole TFS kit that includes the heads, cam, rockers and intake. I'm guessing the heads and intake are pretty much port matched with each other from factory?

If I were to get TFS heads, will any aftermarket extractor fit? I would be looking at getting pacemaker tri-y's. For anyone who has TFS heads or experience with them your opinions/comments are valued.
I have pacemaker Tri-Ys installed in my AU, together with twisted wedge heads. The Pacemakers (p/n ph4001) are a little bit tight in the AU engine bay (you have an AU, true?) but can be "finessed" so that they do not rattle against the body / steering.
Yeah mate I have an AU. So what is with the headers banging against the body? What can be done to ensure that does not happen?
The passenger side collectors can come into contact with the body and the steering arms. It is a very tight fit down that side.
This is no big problem - you just have to get your exhaust shop to ensure there is enough clearance and they can do that by heating and moving them slightly. Note that the clearance will need to take into account a bit of engine shake at idle if you have a bigger cam.
