PRC As Cast Heads Dyno Results on 01 Z06 We just finished dyno testing a production version of the PRC As Cast Cathedral LS cylinder heads & I'm completely pumped up about the results!
The test car is a 01 z06 cam only car with the following mods:
Z06 LS6
243 Heads
Tsunami Camshaft
PRC Spring Kit
TSP Headers & X Pipe
Stock Mufflers
Vararam intake
The only addition was a set of PRC As Cast Cathedral Heads. The car gained right at 30hp & 24lb ft of torque! That's a awesome gain over a LS6 head, keep in mind that'd probably be 45-50 over a stock LS1 241 casting!
The first production run of these heads are expected to be ready less than a month so keep your eyes open for new results very soon!

Dear TSP , you gotta go for a small bore LS3/LS7 heads for the LS1/LS6's "3.905" bore. I would be the first one who buys them! with a small bore cnc'd LS3's, I think they will flow up to 350-370cfm which with pull up 60-80rwhp over the LS1 heads.
so a H/C ls1 with cnc ls3 heads could reach 500rwhp easily

I've heard of them by a friend ...
and as you know , the Mast's are pretty expensive (not worth it) , even more expensive than the TFS's .... while the TFS's , PRC's , AFR's have a much higher flow ....

TFS 215s would outperform small bore LS3/LS7 heads on a 346ci.

Are these stock casting or aftermarket castings?

Nobody has built a ls3 port on a small bore because they cathedral heads we offer now will dominate a LS3 intake port setup IMHO.
This is a complete aftermarket casting head with the ports cast similar to our cnc versions.
