Frequently Asked Questions:

1. What does MLS stand for and what are its benefits? MLS stands for Multi-Layer Steel. These gaskets are made from multiple thin layers of steel, often with an embossed design, providing superior sealing capabilities compared to traditional composite gaskets. They are excellent at accommodating surface finishes, preventing leaks under high cylinder pressures, and resisting heat.
2. Which Small Block Chevy engines is the Fel-Pro 1901 designed for? This gasket is specifically designed for SBC engines with a 4.100-inch cylinder bore. This often includes engines that have been bored over or custom performance builds. Always measure your engine’s bore precisely to ensure compatibility.
3. Can I reuse an MLS head gasket? No, MLS head gaskets are designed for single use. Once compressed, they take a set, and reusing them significantly compromises their sealing integrity.
4. Do MLS gaskets require a special surface finish? While MLS gaskets are more forgiving than some older gasket types, a very smooth surface finish (typically 30-80 Ra for aluminum heads/blocks, 40-100 Ra for cast iron) on both the block and cylinder head is recommended for optimal sealing and longevity.
5. Do you ship Fel-Pro gaskets throughout South Africa? Yes, we offer reliable nationwide delivery of engine gaskets and seals across South Africa from our location in Alberton, Gauteng.
6. Is this gasket suitable for a street engine or only race engines? While essential for race engines, the Fel-Pro 1901 MLS head gasket is also an excellent upgrade for high-performance street engines, especially those with increased compression, aftermarket cylinder heads, or forced induction, where enhanced sealing and durability are desired.
