Top End Kit for Harley-Davidson® Twin Cam® Engines

Top End Kits for Twin Cam
Kit includes Delkron’s Hi-Flow assembled cylinder heads that are made from 20% stronger permanent mold castings and CNC machined for highest possible quality. They have nitrided stainless 2.02" intake valves and 1.610" exhaust valves with increased port diameters for improved flow. Upgraded springs and collars will accommodate up to .640" total lift making these heads a dream come true. Kit is supplied with an "E" style intake.manifold. Cylinders feature centrifugally spun cast iron liners integrally cast to aluminum to provide excellent thermal conductivity. Also includes Wiseco 10.5:1 Compression ratio Piston Kit and Cometic MLS Gasket Kit.

Technical Specs
Bore sizes from 3.875" to 4.125". Compression ratio of 10.5:1 on either kit. Accepts stock rocker arms. However, for better rocker arm alignment on the valves when using high lift cams, choose Delkron's Billet Rocker Arm Supports sold separately (see Related Delkron Products below). Available in natural or black finish.

NOTE* ALL 2008 and later Touring Models must use part number with -8 suffix. These heads are machined to accept the front engine mount.

*NOTE* All Delkron heads are machined to use the 2006 and later Universal intake flanges. Using the earlier Front & Rear intake flanges will not allow proper alignment of the intake manifold. **All Delkron heads require stock rocker boxes be modified for breather channel or the use of Delkron rocker boxes.
