New Advanced Induction Heads
This new addition makes this beast come alive.
These heads are the highly sought after "243" casting ZO6 heads off the LS6.
Sent them off to Advanced Induction for there 232 CNC service.
I had them milled down to 64cc bumping my compression up to 11.0.1 from 9.75.1. (317 truck castings)
New Brian Toole 660 springs, push rods and OEM GM gold LS2 6.0L thin head gaskets.
Ported & polished the throttle body and ported the LS6 factory intake manifold.
Estimate wheels horse power is 500hp. at 4,200 elevation.
This engine is built like the LS2 6.0L engine with a bunch of upgrades and has the Iron block instead of the weak aluminum block.
