Manley Chevy Big Block Street Flo Intake Valves 2.250in Head Dia

These Manley Street Flo intake valves start with a 2.250-inch head diameter, a common size for Chevy Big Block engines looking for improved airflow over stock. They are made from high-grade stainless steel, which means they're built to last and resist the heat and stress of regular driving. The under-head areas are swirl polished, a detail that helps smooth out the air's path into the cylinder, potentially giving you a bit more power and better combustion efficiency. The stems are chrome-plated and feature hard tips, adding extra durability where it counts for wear resistance.

Manley offers these in a 'Street Flo' shape, designed to work well in stock or mildly modified street engines. This means if you're rebuilding your top end and want a solid upgrade without going full race-spec, these valves are a well-built option. They are fully machined to ensure they seat properly and perform consistently. While they are designed for street use, the durable materials and construction mean they can handle the demands of everyday driving.
