I just got a set from TEA with the upgraded exhaust valves. Should be picking up my 408 shortblock next week. Looking to run 20lbs of boost with a 91mm on E85 with them. I'll let you know when once it's running.

I have the tfs 220 as cast heads on my 91mm 408ci camaro. a little bit of port work done and std size ferrea valves. It made 1165 whp at 17 psi so far and im sure will make a ton more without issue if i turn up the boost.
