2003 Escalade? Was it the 6.0L LQ9?

Thanks

You are correct.

Just a heads up, while most Escalades had AWD and the LQ9 6.0, some of the 2WDs had the 5.3. Starting in '05 they're all 6.0s.

Block cast # is 12551364 and the heads are 317's, is it worth $300. has a rod knock. NO intake or acc.

317 heads are not worth $300

Yeah i was thinking 799 heads But the 317s arent a bad head the can flow good numbers with some work.

i thought they came with an LQ4 up to 2004? My 6.0 block is an LQ4, and when I ran the numbers it came up as an escalade block. I thought 05 and newer were the LQ9?
Am i way off?

Actually a friend gave me a few sheets with the differences between LS motors and the 317 heads flow the same as LS6 heads(243's, 317's) but lower the compression.

Anyone who thinks 317 heads arent worth 300 bucks or think that they are inferior to ANY Ls head needs to learn their material. Before you get talked out of the deal check the flow numbers and then realize that LQ9 heads are LS6 heads with .030" more deck thickness minus the sodium filled longer valves. People doing any type of power adder should consider 317 heads with better valves. I love them and will probably use them on future swaps. Just my opinion?

Dude we all know that. Thats old news. The actual reason they arent worth $300 is because of supply and demand. There is a **** ton of 317s floating around in the world. There are not near as many 799/243 heads. Most dont run forced induction, and most dont want to mill 30 to get back to normal NA compression. So no they arent as great as you make them out to be for the average guy.
