you will need the following.. im doing the same swap but with a lq9 in a 07 silverado
L92 gm or cometic gaskets
L92 rocker stands
L92 offset intake rockers
LS3 intake w/fuelrails
Map Sensor Extended harness
SLP throttle body cable braket
You cant use any LS1/LS6 style intake with these heads. Intake port is way diffrent.. Look on slp's website and they have a complete setup for a swap..

i realize i will have to go with the L76 intake. what i'm curious about is if i can use my 42s from my LS1 on it somehow? i will be using a PTM 92mm TB. will my 6.0 MLS gaskets work on these heads? will my injector harness work with the newer style injectors? will my valve covers bolt onto the L92 heads? i'm searching and learning alot. just like direct answers to my questions as well.
You should use the 6.2L gasket, the 6.0L will be too close to the combustion chamber and overhangs slightly. Valve covers will work. Call FIC on the injectors, the height is the only possible issue.
