107" Top End Kit for Harley-DavidsonŽ Twin CamŽ 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. Supplied with an "E" series intake. 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 size is 4.125". Compression ratio of 10.5:1. 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* This kit is designed for 99 thru 06 Twin CamŽ models.

NOTE* These cylinders will not fit stock Twin CamŽ crankcases without spigot bore modifications.

*NOTE* All Delkron heads are machined to accept 2006 and later Universal intake flanges. Earlier front and rear flanges will not allow proper alignment. **The use of any Delkron head will require the stock rocker box to be modified for the breather channel or the use of a Delkron rocker box.
