Frequently Asked Questions
What's included in this gasket kit?
Every gasket, seal, washer, and o-ring required for a complete engine overhaul — head gaskets, base gaskets, valve stem seals, and fasteners.
Will this fit my Big Twin engine?
This kit is specific to Evo Big Twin (1984-1999) engines. Twin Cam and Milwaukee-Eight models require different kits.
Can I use these gaskets for a partial rebuild?
Yes — you can use individual components from the kit. The complete kit is economical when doing a full overhaul.
What is MLS technology in the head gasket?
Multi-Layer Steel (MLS) gaskets use layered steel construction for better sealing under pressure and heat cycling compared to single-layer gaskets.

Installed a new Baker 6spd OD on my 85th Anniversary FLHTC so I replaced the chrome covers and their associated gaskets, all look fabulous tomorrow I'll ride to Illinois and put down about 470 miles to break in the new gears and I'll also find out if all the covers and gaskets on my new tranny top and end covers are sealed and working well. But I'm pleased with how they fit and look.
