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 GM 4.900" stock length LS3 hollow stem valves are 89 grams.
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.

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.

Oh when I first got the heads before I sold them I called TEA and asked if they did a NOS exhaust port...it was in the works should be done by now you guy should look into it.
