Valve 2000 Race UNDERSIZE 9x38.0mm 45 degree Exhaust
[20009EVUS]
$43.00 $39.50

Stainless steel alloy standard 38.0mm exhaust valve for 2.0 Alfas with standard  9mm stems.  

NOTE:  There is a theory that the 2mm smaller 38.0mm valve (standard diameter 40mm) reduces over-scavenging in high compression/RPM engines and yields better performance characteristics.

For more info on valve sizing and cylinder head performance, buy a copy of the Jim Kartalamakis book advertised at the top of this section.
