I’m considering a set for my LS3. Who can tell me the track record of these heads. How many miles do you have on them? What rockers are you using. Any regrets?
Any input is appreciated.

I have these heads on my Custom Built 396" built by Dustin Lee. The Heads built by Tony Mamo @ MamoMotorSports (MMS).
Very happy with performance (690 HP @ Crank 7100-7300 RPM) using T&D RR with Cam Motion LLSR, Very Few miles
Not really a street car LOL. For out of the Box I would use the AFR LS3 Heads, the Last Heads Tony designed at AFR after
he had "Mamofied" many dozens of the TFS 255s including mine. Same price, slightly heavier (denser alloy/thicker deck?) (great for FI).
Just my .02
Good Luck
