For the newbies, please reread Danny's last paragraph. Its the core, the best builder, the best flow bench, the prettiest rebuild will not make a fast q-jet. Borrow a known fast q-jet, buy several cores, rebuild them, run them on the track. Then get the best one done by a good builder. Just my experience. I don't think the same process works for stocker heads any more.
