LQ9 in '05 & '06 Denali?

the 6.2 l92 heads are a great upgrade but you have to get the intake and the rocker arms can be pricey if you do not get them with the heads. They can only be used on a 6.0 or a ls motor with atleast a 4.0 in bore

LQ9's have 317 heads, the same as 02 & up LQ4's.

my 01 6.0 has 317 heads as well

I've been reading on ls1tech that a lot of F-body guys are going with the lq4 and l92 heads and making gobs of power both boosted and n/a. If I was going to spend the money to do a cam and head swap I'd get the stg2 l92 heads and cam combo off texas-speed. $2k for the heads, cam of your choice, valve springs, and push rods. All you'd have left to do is the tune.

It's the high-output version of the Denali motor. It has 345hp/380lb/ft vs 325hp/365lbft. Standard in
02-06 Escalade, 03-06 Silverado SS, 05-07 Sierra Denali.

Some escalade's are 5.3 2WD, wasn't sure if you were aware of that.
