GSC Power Division 3087-8 Exhaust Valve Guides for Honda S2000 F20C/F22C 5.5mm

Vehicle Fitment

• 2000-2003 Honda S2000 AP1 (2.0L F20C DOHC VTEC, RWD)
• 2004-2009 Honda S2000 AP2 (2.2L F22C DOHC VTEC, RWD)

Fitment Notes

• Exhaust position only. For intake valve guides, see GSC part number 3088-8.
• This is the traditional smooth (non-stopper) style exhaust valve guide for the F20C/F22C cylinder head.
• Oversized variants (+0.001" and +0.003" OD) are sold individually under separate part numbers and are not included in this set.

Features

• Manufactured from true C67410 Manganese Bronze for enhanced heat dissipation and long-term durability over OEM cast iron.
• CNC-turned on dedicated precision turning centers, holding some of the tightest tolerances in the industry.
• True-to-size OD minimizes guide boss honing on cylinder heads in good condition, saving machine time.
• Tight through-hole concentricity to OD reduces honing required during installation.
• Shaped to improve airflow around the guide bore - not a direct OEM copy design.
• Compatible with standard 5.5mm exhaust valve stems and common aftermarket valve stem seal options.
• Proven choice for both street rebuilds and high-RPM track builds on the F20C/F22C platform.
• Pairs directly with GSC intake guides (3088-8) for a complete head rebuild set.

Product Description

The GSC Power Division 3087-8 is a set of eight standard-size Manganese Bronze exhaust valve guides engineered specifically for the Honda S2000, covering both the 2.0L F20C (AP1, 2000-2003) and the 2.2L F22C (AP2, 2004-2009). Made from true C67410 Manganese Bronze, these guides provide superior thermal conductivity compared to OEM cast iron - a meaningful advantage on a high-revving engine known for pushing exhaust temperatures hard. The material also offers better natural lubricity, reducing stem-to-guide wear over extended use.

GSC machines these to extremely tight tolerances on dedicated CNC turning centers, making installation more straightforward and reducing the amount of guide boss honing required. The smooth (non-stopper) style is the correct format for the F20C/F22C exhaust side. For a complete head rebuild, pair these with GSC intake guides 3088-8. Whether you're refreshing a high-mileage street engine or building a race-spec S2000, the 3087-8 is a well-established upgrade over worn stock guides.
