Just looking at Summit and I finally see a date for the release of the TFS LS3 heads as 4-8-13, so we finally have another player to the aftermarket head game for 821's.
So the question I pose, stock 4.06" bore and stock 376ci, pick your poision, do you go with the PRC 250's with the 13* valve angle, or the TFS 255's with a 12* valve angle? Let's hear your what's and why's

Prc because trickflow will never release them.
They said coming soon 3 years ago with a ship date. Then they pushed it back again, and again, then said coming soon in December only to push it back twice again.
So yea, by the time their dumbasses release it lsx will be like the sbc - obsolete.
