Very stout combo right there. I agree the Torquer cam seems to be doing quite well with those heads and intake. I'm sure with a larger cam, you'd be knocking on the 500 rwhp door. Impressive numbers nonetheless with the TH400 and 9" eating up quite a bit of power.

This thread seemed to be started a while ago but I figured I'd post some numbers after just getting these heads installed.
Previous setup - Magnaflow Exhaust, Y-pipe, Pacesetter headers, LS1 Intake Manifold, Comp Cams 224/224 114, 363hp/343tq on a mustang dyno
New setup - Custom 3" true dual exhaust w/ Pacesetter headers, LS6 Intake Manifold, 42LB Injectors, Yank SS3600 Converter, PRC 225 as cast heads (milled to 60cc), TQRV4 Cam, 455hp / 423tq on the same mustang dyno tuned by the same shop as my previous setup
These heads seem to be putting out some good numbers...very pleased with them so far.
