    I want stock ls1 head specs...please help guys!

    Pretty simple question for you guys

    What is the port length, height, and width of a stock ls1 head?

    Does anyone have a picture of the ports?

    I just want to "take a look."

    What size are the valve stems? 8mm?

    Any good write-ups on the innovations of the ls1 engine?

    I found this:

    check out the book by will handzel at amazon.com. Cheap and a pretty good read on the LS1 and the history and specs of the motor.
