Agostino Racing Engines Stage3 ported LS1 heads. These are not the truck 6.0 heads, or the 5.3L heads, or LS6 heads. LS1 castings. Information below:


5 Angle Valve Job
Custom Manley 2.08-2.10 Intake / 1.57 -1.60 Exhaust Valves
Custom Double Valve Springs
Titanium Retainers
Custom Port Volumes to match Engine Size and Desired RPM Range
Full Competition Race Port and Polish Intake / Exhaust Ports
Fully CNC Ports & Chambers then Hand Finish to Equalize Airflow

New Interlocking Hardened Valve Seats
Bronze Valve Guides

Viton Valve Seals
Resurface Heads to Desired Compression and Set Combustion Chamber CC

New they are $2,650.00 USD plus Head Core

With the newer heads and the other vendors around, prices have dropped for most comparible heads. There is maybe 2500-3000 miles on these heads


I don't have a flow sheet and there are too many variables that go into reading them anyways. These heads make power. Unfortunately I've never been able to run them to their true potential for one reason or another since i always had the LS1 intake on this year. These were on my 382 All Bore motor. Would work great on some GTO's ;) haha. Heads are still on car but can be removed by the weekend.
