How good are the GM LS6 CNC Ported Cylinder Heads??
Fred Beans sells them for only $989. Part # 88958622. What type of gains do they provide over the stock LS6 heads and how do they compare to your typical "stage 2" type heads??
And most importantly, are they indistinguishable from the stock heads when looking into the engine bay? Reason I ask is I don't want my warranty voided which is the main reason I am looking to these heads.

Oh yeah, I just looked and you're right. I thought that was a little cheap. Why the heck are they quoting per head? Thats like advertising sneakers @ a per sneaker price. Who buys just one. Well, it'd be cheaper for me just to get my existing heads ported than

Right outta the box, stock LS1/LS6 heads are among the best flowing factory heads EVER made. When ported by someone who knows what they're doing, along with a spring upgrade, you'll have a set of heads that will be as good as a lot of aftermarket heads.
