I still have to get a few odds and ends, I want to make sure I have all the good stuff to bolt these Stage 2's on.
probably going with ARP studs over the stock bolts.

TECH Fanatic
Not trying to start anything but I would hope to have more than 400rwhp through a H/C M6 car...
now if i would have had say a 11:1 CR insted of 10.6:1 and maybe a 228 .581 112
i would have expected somthing in the 420-430 range....
but concidering i was on a small buget... $1500 for heads, cam, LS6, pushrods, etc....
thats what i got.....

Here is a dyno sheet using Richard's WCCH Stage 2, 6.0L heads.
The Stage 2 heads were installed on a 6.0L, A4, Truck with a Magnacharger Radix and a Comp Cams 208º/210º .554"/.556" 114ºlsa bumpstick, running 8lbs of boost.
This Cam idled stock and had a very reponsive throttle

Aren't those machining ridges in the chamber going to cause hot spots and potential issues with spark knock / detonation? Just asking the question, so please don't take it as criticism... I could be wrong!
Cheers,

Your question is a valid one. The scallop height we use is a few thousandts of and inch tall. The reason we machine the chambers at all is to make their volumes the same. We've not seen the step over ridges cause any problems with detonation.

What about head porting for much larger cams? Usually people that have the 6.0 heads are running much larger cams than what is being used here. I personally am running a 244/248 .635/.627 112 +4 cam and am in the market for some porting (to match the 4.060 bore I'm running) and milling to get my compression up a bit. Just wondering because I'm trying to explore the options I have right now and it would probably help a lot of others out as well.

For engines with cams as large as the one your running we would recommend upgrading the heads to a stage 3 setup. The valves are upsized to 2.08"/1.60". They flow over 330cfm and carry the flow peak over .600" lift. Unfortunately there's a higher cost involved due to the machine work required to fit the larger valves.

My apologies. The cost for upgrading to Stage 3 runs an additional $275.00 per pair. Your total for completed heads will run $1575.00 per pair with exchange. Sorry for any confusion.

I just wanted to add that the more I compare my flow numbers the more I feel like these WCCH Stage 2's are everything I was looking for in a head. I realize flow benches and the manner in which the test is conducted make differences. I am going off of the data posted in this section.
So, thanks to Richard for a fantastic set of heads, and thanks to the LS1Tech members who have provided us all with the data for which to compare
as always, the proof will be in the pudding

Moregrip,
It looks like I need to go pay a visit to your head vendor!
This looks like some really good stuff and the flow numbers are great!
Keep us informed about your numbers and don't get arrested.
Warp 10 Always!
