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.
