TF CNC 225's or PRC 227?
TF CNC 225's or PRC 227? Looking to get the most power out of this LS2 
. I am already running a VRX-5 cam, SLP LT, and a SLP UDP. Will also be adding a FAST 102, FAST 46# injectors and a Spintech exhaust. Now it is just a matter of which head? I want to reach that 500 RWHP.

The advantage to the PRC 227 is it features a smaller chamber option for exactly this application. You can't mill the TFS enough & keep your p/v good to get compression where you need to be. The PRC 227 head will keep good p/v thanks to the little bit smaller valve, and it will start with a 62cc chamber so your compression is in good shape without milling!

Thunder has the TEA TF 225 for a really good price. Has dual springs all the goods you would need to get to your goal of 500rwhp. I have a mild size cam and a ported fast 92. With the size of cam you have, I have know doubts that you will reach what you want. When my car was tuned it put down 497rwhp before the smoothing factor and it was 90 degrees+ with TX humidity. These heads or ETP would do it but ETP is more cash. TEA 225 are around $2395.
