PRC 2.5 5.3 vs PRC 215 heads.
I have the 2.3 5.3 heads right now and while they are performing great I feel they are the next bottle neck in my set up. How much should the PRC 215s give me over the 5.3 heads?

Gain isn't worth the cost, a bigger bump stick will lend you better results. A Martin@tick, patG, EPS, Brian Tooley, or Ed Curtis bump stick will get you the best bang for the buck results.

I wouldnt change a thing in that setup with the power you are making. Maybe look into a procharger w/meth if you want more power. 464rwhp is awesome for those mods and I bet the car makes power everywhere with that cam.

I'm not completely opposed to swapping the cam out also for a bigger but not donkey dick sized cam. The main reason for wanting to change heads is that the setup is a bit over 5 years old minus the intake. Would it be plausible to gain 20-25 hp with a better set of heads and say a 234/242 cam?

Yes. Your cam now is pretty mild, so adding 10 degrees of duration to intake/exhaust... it certainly won't drive as nice, but it will make more power. And the heads could definitely add to that. Although, I'm not sure the heads need a wide split. You might be able to do a 235/238 111 cam with the PRC 215s and make 480-490.
