Holley headers and mounts

They're going to hit the crossmember.

I disagree. The Holley cross member works perfectly.

I was talking about the knock sensors hitting the front crossmember (where the engine mounts are). If they don't hit, they'll be a mf'er to change!

You should have ZERO fitment issues with headers as the Gen3 LS based engines have the knock sensors in the intake valley, and not in the heads. The wiring connects both, and when intake is on they disappear.

Nice set up. Is the JIC 90° fitting on your valley cover your turbo return?

Nope, courtesy of MotorheadMike's knowledge of the LS platform, that is the cheap man's LS6 PCV/blowby system.

Gotcha. I'll get a pic today. I don't think it'll be that tight by the motor mounts.
