WEAPON-X: Ported LF4 Cylinder Heads [ATS V gen 1, LF4]
Vendor: WEAPON-X Motorsports
The 2016+ Cadillac ATS V has some impressive and unique heads with dual cams, direct injected pump, and integrated exhaust runners built in (which helps with the space); however, really limits the flow characteristics. Couple this with some very mild low lift camshafts, and you have yourself heads that flow 205CFM.
I've had a set of heads at my cylinder head porter working on the WEAPON-X proprietary head port and camshaft specs and I'm happy to say the cylinder heads are completed and the gain was over 30%!
Here's what we do! Fully CNC ported intake and exhaust ports, custom intake valve job, custom full radius exhaust valve job, intake and exhaust bowl blending, optional milling for increased compression ratio.
Cam kits include 2 intake and 2 exhaust camshafts and optional 30% overdrive fuel lobe for E85 and higher boost pressures. This option adds $250 to the overall cost not included below.
