Not an easy feat: Through a combination of our 60+ years experience in the automotive high performance machine world, coupled to our constantly evolving state-of-the-art machine equipment, our S63 program affords you precision and flexibility not available to many competitors. Our heads have always been a popular choice- even when simply rebuilding an engine as fantastic value in performance at every level, we have elevated the performance and reliability of BMWs greatest NA achievement.

Unlike many other BMW cylinder heads, the S63 has several specifications that are already well suited to even full-race use. We offer performance gains at only a slightly higher price than stock rebuilds (like heads that are still Stock Class legal) as well as full-blown options from everything from street cars, forced induction, to standalone ECU equipped full-race configurations.

All of our S63 Performance Cylinder Heads feature at least the following:

• Complete Disassembly & Cleaning
• Comprehensive Leak, Crack & Pressure Test
• Inspect All Components For Irregular Wear
• Our extreme performance Multi Angle Valve Job using Serdi Equipment
• All New VAC Valve Guides
• VAC Viton Valve Seals
• Reconditioning & Blueprinting of Your Valves (VAC valves also available)
• Testing of Your OE Springs (upgraded VAC springs available)
• Trueness Checked & Resurfaced Mating Surface
• Un-shrouding of Valves (on request as this is not legal in stock class)
• Attention to Potential Hot-spot Areas and Chamfering
