TSP doesn't require a core charge, while TEA does, which makes the TSP much cheaper.
that said, I own the TSP heads and am not happy with the overall performance. At this point, I don't know if it's because of the cam I have or not.....
I have a C5 with an LS3 conversion using eagle rods, mahle pistons. I bought the TSP heads, milled them to 65cc, and am using a 230/234 114 LSA cam. I have LG pros on the car with stock Ti catback. The LS3 intake is ported. I have a vortex ram air intake and volant air bridge.
Here is my dyno graph:

I'm going to try the G6X3 cam, if there is no appreciable improvement in power, the heads will be sold and I'll go another route.

Something is not right here but I don't think it your cam because your #'s should be WAAAAY higher anyway. I have the same cam on a 111+2 and made 434/400 on a 346ci motor. When I port my FAST and add an 85mm maf and FT 95mm lid I should be looking at 450.... IDK what to think about this one.... Any track times??????
EDIT: Stalled A4 car with 220 TFS as cast heads on 24lb heavy *** replica wheels.......

I just made 537/501 with TSP PRC L92s.
They seem to be a decent head.
Not the best but still very nice.
For the money I am happy with them.

I have no problem putting the TSP/PRC L92 heads against any heads being discussed in this thread. We've made great power time & time again with these heads. My personal 2010 makes 500rwhp with almost stock compression on PRC LS3 heads. We're working on a aftermarket casting LS3 head that will be available very soon as well!
