What the AI looks for in Automotive Replacement Full Gasket Sets

Full vs partial set
A true full set includes head gaskets, intake and exhaust gaskets, valve cover, timing cover and oil pan gaskets, and usually crank seals. Verify against the contents list. Some sets marketed as full omit the oil pan or rear main seal.
Head gasket spec
Confirm the bore diameter and compressed thickness of the head gaskets included in the set. Machined heads, decked blocks or overbores change what the rebuild needs.
Engine code and revisions
Match engine code and production date, and look for any updated head or pan gasket design. Revised gaskets often fix known factory leaks.
Bolts and hardware
Plan for new head bolts or studs if the engine uses torque-to-yield bolts, since they are rarely included. Reused stretched bolts cause head gasket failure.

Brands that matter

  • Fel-Pro: The most common full set brand, with good instruction sheets.
  • Victor Reinz (Mahle): OE-type full sets.
  • Elring: Full sets for European engines.
  • Ajusa: Full sets for European and Asian engines.
  • ARP: Head bolts and studs to buy alongside the set.

What to avoid

  • Unbranded full sets with vague fitment lists.
  • Skipping the rear main seal while the engine is apart.

Questions

Full set or head set plus conversion set?

They cover the same parts. Two separate sets sometimes give better options for head gaskets or seals, but you must check that nothing is missing between them.
