Description
A CNC-ported Stage 3 cylinder head for the 1G/2G DSM and Evo 8/9 4G63, built to order and configured to each customer’s power target rather than a one-size package.
Every core is inspected before custom CNC porting gives full control of port shape and finish: intake ports gain over 40 CFM and exhaust over 50 CFM versus stock. A competition multi-angle valve job precedes assembly with stainless steel valves, Magnus beehive valve springs, titanium retainers, bronze guides and valve stem seals, supporting power to 11,000rpm. Designed to work directly with Magnus cast-aluminium or sheet-metal intake manifolds. Backed by Magnus’s lifetime guarantee.
Features
- Custom CNC porting: +40 CFM intake, +50 CFM exhaust
- Multi-angle valve job, stainless valves, beehive springs, titanium retainers
- Supports up to 11,000rpm
