SCCA LEGAL SIZE

This standard diameter 37mm stainless steel valve fits all 1600 and 1750 engines.

• 45 degree seat angle improve flow
• Special back side shape improves flow
• Some builders claim that 1mm oversize 38mm valves over scavenge and reduce low end torque

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