Valve 1300 Oversize Street/Race (101/105) 9 x 39.5mm Each
[1300IVOS]
$0.00

For all 101/105 1300 engines.  Especially effective with our 1400cc kit.

These oversize intake valves with 45 degree seating greatly enhance intake flow at all RPM, with or without reworking the ports. 

  • These 39.5mm valves fit comfortably on original 39mm seats with a .020" margin overlap.  This margin increases initial flow.
  • Use with stock 34mm exhaust valves with original 30 degree seating.
  • 9mm stem undercut to 8mm in port for better flow.
  • Requires 9x42mm race guides to increase flow.
  • Use one of our cam combos:

          424/425 for best performance upgrade

          425/423 for mild performance upgrade
