NEW! 103" Hop Up Kit

We now offer the owner’s of late model 96” engines a means to achieve a dramatic improvement in horsepower and torque with our new 103” Hop Up kit. These kits feature Delkron's Hi-Flow heads with AV-V black valves and manganese bronze guides. Upgraded springs and collars will accommodate up to .640" total lift making these heads a dream come true. Kits come with an "E" series manifold to match port openings and Cometic MLS gasket kit along with 10.5:1 Ross Racing Pistons. These kits are available in Black or Natural finish.

NEW! 95cc CNC’d Combustion Chambers! We have brought our cylinder heads to another level. By performing our patent pending CNC procedure on our already proven cylinder heads we have improved combustion through increased laminar flow. We ensure exact dimensioning and reliable repeatability, with the added benefit of increased horsepower and torque. Throughout our testing we were able to achieve a 4% horsepower and a 6% torque increase simply by changing the combustion chamber! These heads use the same components as our “as cast” heads.

NOTE: All testing was performed on our Land & Sea eddy current dyno using our Delkron 107” kit with Red Shift 577 cams, Twin Tec Ignition, and S&S G carb in a 2000 FLHTC. Before head change HP=99.79 @ 5300 rpm and Torque=121.05 @ 3900 rpm. After only a cylinder head change, HP=103.5 @ 4900 rpm and Torque=128.25 @ 3600 rpm.

Technical Specs
Intended for use on late model 96” Harley Davidson engines with 4.375 stroke,but for 2008 and later Touring Models use part number with -8 suffix.

*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.
