Frequently Asked Questions
What gaskets are included in this kit?
Complete motor gasket set with multi-layer steel (.045) head gaskets plus all other critical engine seals for a full rebuild.
Will this work on a bored or stroked Evolution?
This kit is designed for stock bore and stroke Evolution engines. Aftermarket boring or stroking may require different head gasket specs.
Do I need a torque wrench for installation?
Yes — proper head bolt torque sequence is critical to seat MLS head gaskets correctly and maintain compression.
Is this a complete gasket kit or just head gaskets?
This is a complete motor gasket kit including all seals needed for an engine rebuild, not just the head gaskets.
