They arent out yet. Trick flow has them in the catalogue, and flow data which is impressive.
I was gonna buy the tfs ls3 heads, but holy ****, they said 'coming soon' last christmas, then this november they said 'coming soon' again, now here almost 6 months later not ****. so yea, **** them they are 6 years late to the party

[SIZE="4"]Jason,
Glad to see these look so promising. Did you guys ever get those builds finished that you mentioned in your first post? Dyno #s.........??????/SIZE]You've posted in the beginning of the thread about some builds going on. Why haven't you'll posted data that you promised? Did the numbers end up being low/soft? LOL

Ordered my PRC 255's dyno numbers coming beginning of march.
In theory they are supposed to flow more then MAST black label heads which cost 1k more. This should be interesting.
