Top End Rebuild Gasket Kit

for Shovelhead

Pkg: 1 kit  – Part# 38438a (Replaces OEM 17034-80) 

This is a complete Top End Gasket Kit for the Shovelhead Big Twin. It should contain all the gaskets, seals and O-rings you need to put your Shovelhead top end back together securely.

The head gaskets are a flexible material similar to Teflon, reinforced with steel mesh core. The steel mesh is molded into the gasket material so that it would be very difficult for a head gasket to blow out. We measure the thickness at approximately 0.031″ (0.8mm). This type of gasket should allow you to pull the heads off again easily without them sticking.

This kit has 2 sets of valve stem seals!
The first set are 3/8″ x 0.625″ seals that fit newer Shovelhead engines from Late 1980 when Harley first starting installing them.

The Second Set of Valve Stem Seals is for the older engines that did not original have factory-installed seals. This set is made of High Temperature Viton (the blue ones) with a spring-loaded aperture, encased in a steel body. You should find these seals very easy to install. The seals for the older engines are 3/8″ x 0.562″ and normally fit Shovelhead engines from 1966 through Early 1980. However… if someone has machined the casting to install some other size aftermarket seals, these standard replacements (ref. 18001-48) may not fit your engine.

For a kit with only 1 set of seals please buy one of our other kits #38438 (L80-84 factory style seals only) or 38438b (1966-E80 aftermarket sty le seals only) – at a few dollars lower price.
