I have a set of out of the box TrickFlow 235's on my LSX454 and it threw down 625 RWHP running thru a Fast 90. Torque is HUGE under the curve, over 500 RWTQ at 3,500 RPM and peaking right at 580. Put a sheetmetal intake and that power goes up.

I'll take the TrickFlows.

For boost AFR's are def the best IMO. They have a thicker deck & will hold the head gaskets better.

+1 the only thing I've seen come close are the All Pro LSW heads. Between the two if I was on a budget I'd take the All Pros.
