CNC'd L92s by WCCH Wanted to share with yall my L92's I just got back from Richard at West Coast Cylinder Heads. These are going on my 408/4L80e project going in my 2006 Crew Cab 1/2 ton. I bought these heads bare from GM and sent them to Richard and he did all the cnc work and they turned out awesome. They flow 345 cc on the intake and 245 on the exhaust side at .600 lift on my 408. If anyone is wanting some bada$$ work on some heads, hes the one to send them to. Here are some pics of before and after.

I think because that area doesnt need much work done. I put a set on our 2wd s-10 blazer at the shop and I can tell u wcch heads are definately worth using. Our blazer with a stock bottom end 427, wcch stage 2 l92, with a nice size cam went 10.32@130 in the quarter and the blazer weighs 3500pds. We also have a powerglide with a 4000 stall in it. Im hoping once we can a different cam, and a different tranny we will see a 9 second pass. Reguardless those stage 2 heads are badass.

+1 for Richard at WCCH. He did my 245cc Edelbrocks, and is one of the best in the business. The devil is in the details when it comes to head work. There is considerably more work in the valve job, blending the seat, working the guide and subtle massaging in the right places than meets the eye. Hogged out and and polished isn't always the best solution for maximizing performance, even though it looks pretty.

Congrats !! Richard and WCCH do quality work, we run his All Pro heads on our shop car and install many of his heads on our customer cars.
He takes a great approach and doesnt just hog them out to make a flow number on a bench.
There is so much more to porting a head than hogging out an intake runner, its good to have a source like him when there are so many people just porting the crap out of heads to get some flow number and then they stuff in a huge cam and wonder why the car is slow on the streets.

They look good. It is wise not to take alot of material out of the throat area. GM heads are thin in this area. Just ask me about that issue. Long story. Hey check out my L92 build for pics of my heads and engine. I had my chambers fully polished and coated.

Heads looks GREAT!!
My Cartek L92's work great too. You can runs 9's for sure with these heads N/A through the stock intake and keep a hydraulic set up with great street manners.
Good luck with the motor.
