Got my PRC Aftermarket 260cc LS3 Heads Today - Pics So theres not many people out there with these heads so I figured I would post up some pics and specs not otherwise found on TSP's website.
First impression, NICE! Heavy, solid, good quality. The CNC work looks prestine the assembly looks flawless, if they perform as well as they look I'll not feel to bad about dropping $2500!
These are the 260cc version, 2.185 intake 1.60 exhaust valves, hollow stem, stainless steel.
Intake runner is 260cc, Exhaust is 90cc
Intake valve weight (hollow stem) is 97 grams, solid stem are 118g, Exhaust valve is 92g
13 degree splayed valve angle
61cc chamber

Glad you like them. The cool thing is they have modified valve locations & angles to maximize power. The intake runners are even smaller than a stock runner & still move huge air!

I got my 255's in a week or two ago. They are very nice heads & the best bang for the buck in this area on the market in my opinion. I couldn't be happier with them. These are going on my LsX 403 Methanol/ 101mm setup.
OP, what setup are you puting togather with these? FI?

My PRC's are top notch. One look at the process these heads go through to ensure quality, really lets you know your getting a great deal on a great cylinder head. Texas Speed FTW. They spared no expense, and went great lengths to get these out on the market along with other MFG like AFR and TFS MAST. I have a feeling we will start seeing them more and more in the future.
