These are a premium high performance stainless steel solid stem intake valve replacement for your less than reliable hollow stem valves. We spend alot of money for our mod cars, the last thing we want is to have a OEM hollow stem valve fail, and make a mess, damaged head, piston, cylinder wall, etc.
The standard stock size is 2.165" and our oversized valve is 2.200"
Sold individually. A whole intake set would require 8.
