WCCH heads are on ! New heads are on, fired up first try ! 
West Coast Cylinder Heads (WCCH) 71cc chamber CNC Stage 2 LS1 5.7L cylinder heads. Rev stainless valves 2.02"/1.57" (stock sizes), Crane dual springs and titanuim retainers, hardened 7.40" pushrods. It's 9.8:1 compression now which is much more boost-friendly.
Brought it up to temp while topping it off with Dexcool/h2o and parked it for the night to heat cycle the springs.
Big thanks to Ed for his help, and to Ben/Bombguy for hooking me up with the stock length hardened pushrods, giving a hand with the exhaust and loaning me a replacement rocker arm bolt (#8 intake was rounded, broke three Craftsman sockets trying to get it loose and finally got it with a 5/16" impact socket and a breaker bar !
)
Here are some pics :
I will be changing the pulley setup for more boost and getting it tuned soon.
Cheers,
Rob (Bad30th)

I have a Greddy catch can, the heads were baked with oil before the catch can was put in place. Hopefully the new heads will stay nice and clean ! 
I'm sure the stock rockers will be fine, they've held up in a lot nastier applications than mine. Just gotta keep an eye out for needle bearings on the oil drain plug.

Let us know how she runs. Richard does great work. He has worked on mine and all my racing friends heads. We have used stock rockers at over 650rwhp and no issues. They will hold up.
