what heads do i need?
I have a 2005 gmc sierra with cracked castech heads at the oil drain (lucky me). Looking at this https://www.performancetrucks.net/fo...d.php?t=434396 , it looks like to remain stock i want either 862 or 706 heads. Which ones did i have? Whats the difference? I have the flex fuel version of the 5.3.

If you're wanting to upgrade, pick up a set of 243s or 799 castings and have them milled .020 to keep the CR the same as stock, or if you actually want to keep it truly stock, you can pick up 706 castings on ebay all day for next to nothing.
Regardless, welcome to the forum, if you have any questions don't hesitate to ask a lot of very knowledgeable people here
