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 them on my AES 390, got them because of the big deck they have. They say they flow pretty good numbers also. I still need some things before it gets to the dyno though.

AES is building my 398 with the "as cast" TFS 220's 65cc. Told i won't find the limit anywhere under 1500fwhp with a 91mm turbo.

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.
