489ci tall deck... ...mildly ported stock intake

What spacer kit did you use to get the intake to fit?

But with angle milled head like I have, I would go with full .400 thick spacer.

489ci tall deck forged internals internally balanced, race rite oval port heads and topped with very mildly ported stock intake with ls3 throttle body grafted on. Running and majorly tuned but still finishing details and need to finish spare 4l80e build before proceeding with boost. Turbo that is to go on is S485 V2 104 TW 1.32 A/R T6.
I keep looking for different intake optopns to get away from the stock piece, but not many options for a truck use.

Hell yeah man that's going to be awesome.
