I couldn't find a thread like this, so I Figured i'd post one up
So my Trickflow heads arrived today. I figured i'd post up a side by side of them next to your standard 2v PI head. These are heads off my lightning, but for all intents and purposes, they are the same heads as your 99-04 mustang.
First off a bit of info.
The Trickflow heads, out of the box feature a 1.85 intake valve and a 1.45 exhaust valve. the PI heads sport a 1.78 intake and 1.33 exhaust. Most ported PI heads feature a +1mm larger valve, the trick flow heads are about 2.5mm larger.
Here is a shot of the flow numbers on Ported TF's, Stock TF's and Ported PI heads

Now for some comparison shots of the heads side by side
I am very excited to get these heads on my shortblock and get this running.
Trickflow has redesigned the combustion chamber on these to get rid of the plug boss to help ward off detonation and headgasket issues that PI heads are known for. They've also moved the intake valve to help with the valve shroud issues.
