Fel-Pro 1010 is a performance head gasket built for Small Block Chevy combustion sealing in C4 Corvette applications with aluminum cylinder heads. Its steel core laminate body, pre-flattened copper wire ring, and non-stick coating help control leaks around heat, pressure, and less-than-perfect deck surfaces while supporting easier service during rebuilds.

Fel-Pro 1010 Technical Specifications:

• Fits Chevy Corvette applications from 1986 through 1991 with aluminum cylinder heads.
• 4.166 in. gasket bore, equal to 105.816 mm, supports engines with a maximum bore up to 4.155 in.
• .039 in. compressed thickness and 8.900 cc compressed volume help maintain a known combustion chamber stack height.
• Steel core laminate construction adds strength for performance Small Block Chevy use.
• Pre-flattened copper wire ring combustion seal is designed for aluminum heads and helps reduce brinelling on softer head surfaces.
• Copper ring design helps move heat away from combustion hot spots around the cylinder opening.
• Non-stick, anti-friction coating helps seal minor surface imperfections and aids removal during frequent engine teardown.
• No-retorque design uses a strong core structure so head bolts do not need a retorque after installation.
• Embossed Printoseal sealing beads are placed around vital sealing areas to help block oil, coolant, and combustion leak paths.

Best suited for performance rebuilds where aluminum head protection, heat transfer at the fire ring, and clean gasket removal matter. Verify engine bore, head material, deck condition, and required compressed thickness before installation.

Intended for Small Block Chevy engines in 1986, 1987, 1988, 1989, 1990, and 1991 Chevy Corvette models with aluminum heads. Also noted as compatible with aluminum blocks using liners when bore requirements are met.
