Where are you seeing stuff about poor quality? All of my stuff has been great and I don't think I've heard of any unhappy customers...?
I am a bit scared of TF stuff nowadays though with people on the forums talking about bad quality (fit and finish).
The stuff looks great in the promotion pics though.
honestly... nothing
and hoesntly they dont have anything for current trick flows
Oh, I think CNC has long surpassed hand porting. I'm sure there is some hand blending that goes on during the development stage of the prototype ports, but I'd be willing to bet that the majority of the high end stuff is developed with flow analysis software, modeled in CAD, and sent straight to the CNC machining center.
Yea thats what i was getting at.
Then they are cleaned up by hand after the CNC is done. Hand porting will never be dead. Its kind of a lost art, but someone has to hand port the casting before the CAD guys can model it.
... And the cad guys design the rough port before the porting guys get their hands on it.

Uh, so let me get this straight, no pun intended. All this time these canted valves that everybody raves about that"unshroud the valve from the cylinder" are being improved upon by lessening the angle from 13 to 11, and 17 to 15 degrees? Interesting.
In other news, AFR just redesigned their line up as well, improving their SBF heads. The 225 race head was replaced by a smaller port size that flows more, and there is a 195 now that flows in the neighborhood of 305-310cfm.
It seems this is the year everyone is stepping up their game!
valve angle goes the other way lower angle the better is a rule of thumb... IIRC the valve angles on the race car are 10* and 7*Uh, so let me get this straight, no pun intended.

Screw it... I'm going to get me a set of ProComps and call it a day.
Save the money and port some GT40s dood. They make hella power.
Too spensive!Gonna find me some E6s, unshroud, and do a 67 angle valve job on em.
Man my cousin's brother in law said to use truck heads off a '75 Econoline van cause they're cast from the old Mexican 290 HiPo police interceptor heads that flowed like 350cfm without porting. They're supposed to be made of magnesium which is stronger than aluminum and lighter than iron. I think they had like 2.20 intake valves and like 1.90 exhaust valves IIRC. You probably need to use P swap headers on them though to clear the duel spark plugs per cylinder.

I've got a set in my garage, let me know when you're ready to get serious.
