Hi Mate!
I'm building an LY6 for my 04 GTO, I was told to not use the Ls2 knock sensors. Instead relocate the Ls1 knock sensors to the Ls2 knock sensor location.

If I can think of anything else I will let you know.

Good Luck!

cool that saves a few $$$
Do they bolt straight in or do we need to drill out and retap to suit the LS1 sensors ?

Ls2 lifter trays are required as well, ls1 trays won't fit apparently.
