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. Cylinders feature centrifugally spun cast iron liners integrally cast to aluminum to provide excellent thermal conductivity. Also includes Ross Racing Piston Kit and Cometic MLS Gasket Kit.

Technical Specs
Bore size is 4.125". Compression ratio of 9.5:1. 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 Cam® models.

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

*NOTE* When using any of our DELKRON cylinder heads on 2006 and later models you must use the 2005 and earlier intake flanges (distinguished as front and rear). The later universal flanges will not allow the intake manifold to seat properly, possibly creating an intake leak.
