Good luck guys and please keep us posted with the numbers..
Blue99fbody it took 3 weeks for PRC 237 heads to arrive to Saudi Arabia I'm sure you'll recieve your in less than two weeks
I will post some results from my friend's TSP 408ci PRC 237 and TSP Gaint very soon..
The only update I have thus far is that they were on my motor on LME's engine dyno. My motor is an RHS block 408 (4.125'' bore x 3.819'' stroke). It's 9.5:1 compression (I've got a 91mm turbo waiting for it). But the motor made 550ish which I thought was pretty decent considering that it is a turbo build.
However, on the last re-torque a crack was discovered the the casting as it pissed water all over the place. That deficiency has been corrected according to the guys at TSP and they sent another set of heads to LME for me. If you guys are waiting on boosted results, it'll be sometime in early 2012 before I can do that for you due to my being deployed currently.

I'd still like to know the deck thickness of them. Guys that are going to run high boost NEED the increased deck thickness and if these heads don't have .750", then I'll scratch them off the list.
The minimum deck thickness on the PRC aftermarket castings is .750" and in the critical areas will be more than that!

That is great to know. I will definitely be pushing these heads pretty far once I get back home and I'm very confident that they will do a great job for my boosted application. I will keep you guys updated as my build progresses more as it seems that there aren't many results for these heads.
