Trick Flow Specialties TFS-30410010 Trick Flow® GenX® 195 Cylinder Heads for GM LT1 | Summit Racing

Those are the heads. I ran them for about 10k, maybe even a little less. Just swapped over to LE2's. On the driver's side head, the center intake hole has been helicoiled and you have to grind the intake just a tick to get it to fit. Otherwise great heads and in great shape. Served me quite well on my 383. Offering them here before I put them on the Impala SS facebook page.
