Has anyone actually upgraded from the PRC 5.3 2.5 heads to the Trick Flow heads? Do you have dyno numbers from before and after the swap?

Given that the TFS heads are not OE castings and also involve installing aftermarket roller rockers, I can imagine that the HP gain would be at least 10 - 15 rwhp more. For only a 10 - 15 hp gain, I'm willing to save the extra $1,000+ on my head swap and then just put the money to my nitrous setup. Of course, if the TFS heads net a 30+ rwhp gain over the PRC heads, it might be worth holding off on the N20 for a bit.

I would be interested in number also.I'm looking at AFR for a Procharger and like that they are thicker casting.
