If someone would pull the trigger on my stock LS3 heads/intake in the classifieds, I would order the TFS right away.

Subscribed to this thread !!! I found the part number for these as a bare head ... Does anyone know if Trick Flow will sell a bare as-cast version of the TFS LS3 heads ???
My TEA TFS 235 head swap got de-railed by a clutch/trans issue...had to sell them but it worked out good...wound up going to guy who had the bottom end they were spec'd for anyway...I'm gonna resarch TFS LS3 options now...had been looking into having a set of Warhawk LS7 heads done for my bore (med bore) but not anymore

The TFS heads have LS7 length valves, so the GM LS3 valves won't work. However, GM LS7 titanium valves with the head diameter turned down will work.

TEA will have an option for hollow stem intake valves for these heads, I'm sure AI will be able to supply those as well.
Manley has a hollow stem LS7 intake valve(11688H-8)110g...those could be turned down to work as well correct??Solid Exhaust(11679-8)103g too??

Yes, that's correct.

The REV hollow stem valves are supposed to be closer to 100 grams, but I haven't received verification of that, nor have I been able to weigh them myself.

The REV valves came in but the back cut or 45 width's were incorrect. They're going to regrind them and flow check them to see if they'll work.
