Head Machining & Upgrades

Specialty-Machined

Flow characteristics of factory cylinder heads are often times restricted and suboptimal. Reasons for this include regulations, design flaws, and manufacturing constraints. Porting and polishing will breathe new life into your motor by increasing flow dynamics of both the intake and exhaust ports of the cylinder heads.

More efficiently flowing gases mean a more powerful engine, ready for whatever application is intended for it. From daily driving to podium finishes in competition, don’t miss the benefits of this machining process.

• Porting & Polishing any 2.0L or 2.5L heads – $1200.00

• Bowl Blending for intake & exhaust ports – $750.00

Please allow up to 21 days for service to be completed. Ask about our camshafts and other parts upgrades for your built motor!
