This Chevy LS engine rebuild and performance manual covers:
- Chevy LS1 5.7L 1997-2004
- Chevy LS6 5.7L 1999-2004
- Chevy LS2 6.0L 2005-2007

- Chevy LS9 6.2L 2009+
Gen III GM engines represent the previous generations of GM "small-block" engines. Since the debut of the LS1 in 1997, the LS family has gained substantial momentum in the performance aftermarket.
Gen III and Gen IV engines include more than 5.7L and 6.0L versions, and while the book's introduction provides overall background information on the entire LS series, the focus is on building a Gen IV LS2 in a performance approach as an example. All assembly techniques apply to all LS variants.
The LS generation of Chevy/GM motors have set new standards for engine performance in the enthusiast and racing worlds. In this how-to book, engine builder and writer Mike Mavrigian features a 625 HP buildup of an LS2 with part numbers, clearances, specs, full assembly, and dyno test results.
The procedures and aftermarket performance parts selections apply to all LS engines, including the LS1, LS6, LS2, LS3, LS7 and LS9.

OEM AND AFTERMARKET CYLINDER HEADS
GM's production LS cylinder heads are great pieces, the mostly notable of which is probably the L92 head. These heads produce decent power, but if you really want to play with the big boys, you'll have to look toward the performance aftermarket.
TABLE of CONTENTS:
Aftermarket firms such as Trick Flow, Dar, RHS, World Products, AFR, Edelbrock and Pro-Filer have studied the OE heads in terms of port volumes, port angles, valve angles, airflow and combustion chamber design and tweaked and improved them to a whole 'nother level.
Bear in mind that when you purchase new cylinder heads, you often have a choice of either complete heads (already fitted with valves, springs, keepers and retainers) or bare heads.
Purchasing bare heads allows you to custom machine to incorporate individual tuning modifications, and to select the specific valves and springs that you prefer for your application (for instance, a builder may prefer a specific brand and material for his valves, or may need to install valve springs that match the operational needs of a specific camshaft).
Heads that are listed as CNC machined have been machined (intake and exhaust ports and chambers) to exacting and matching specifications (essentially "blueprinting" the heads).
Some manufacturers offer cylinder heads that are listed "as cast." This refers to a very exacting casting process that mimics a CNC-ported head without the need to actually perform extensive CNC machining.
