Are there any issues with running LS6 (243 castings) on the LS3/L92 block? I know the bore is larger. Wondering if that's going to be an issue. Can't get the L92 heads yet, so I'm planning to use my current LS6 heads. Thanks.

they will fit with no issues but you will need to use the LS6 intake or the LSX 90mm Fast intake with the LS6 heads.

With the smaller combustion chamber {243's} your compression ratio will be higher.

does anyone know how this combo would fair with an LS7 cam, what push rods and rockers would be good. Any advice would be helpful, Im new to LS motors, I have an 04 CTS-V and have a cylinder 2 misfire issue and was thinking instead of fixing maybe a good time to do a swap.

KEEP IN MIND AN LS7 cam is rated on a 1.8 rocker ratio... so it will act like a smaller camshaft... you can do the math and see what it will calculate to
