    I was wondering where I could find out the specs on the stock heads for the 4.8l engine. I've done alot of searching and come up with zilch. Thanks for the help.

    Welcome to the club, Pick up a book called How to Build high Performance Chevy LS1/LS6 V-8's by Will Handzel. At one time Handzel was in charge of GM Performance. You can get this book from a GM dealer part # 88958786.
