Default New! Trickflow LS3 Heads! 382 CFM!
From the makers of the baddest cathedral cylinder heads on the market, comes the all new Trickflow LS3 Cylinder Heads!

Any comparisons with other ported LS3 heads? Torque/HP curves? Really like my TEA Stage II LS3 heads on my LS7, but am curious about the new TFSs. Thanks.
