Note:
These are correctly profiled jets made specifically for the Rochester Monojet carburetor. Rochester products made several different styles of jets for use in Quadrajets, 1bbl and 2bbl carbs, each with there own unique leading and trailing profile on each side of the jet orifice. Be careful as all the various styles will physically interchange and for example, they could all have a .070" jet orifice but due to the leading and trailing profiles being different, each style will have different flow rates.
Make sure that you are using correct metering jets in your carburetor by using QuadrajetParts.com jets.
