Product Description

Special Retainer & Lock kit for staggered tip length SBF valves

RETAINERS AND LOCKS FOR GT40P

FITMENT: SB Ford engines with .393”/.393”

Kit comes with 16 retainers and locks for SB Ford engines running .393" tip length valves on both intake and exhaust.

 

Early SB Ford 302 engines came with .393" tip length valves on both, intake and exhausts. Later SB Ford heads used staggered tip length valves of .393" intake with .481" exhausts.

This listing is for SB Ford heads which have .393" tip lengths on both, intake and exhaust valves. If your application has staggered tip lengths, look at part # SRK-749

This kit will roughly produce around: 1.800” installed heights. This is a generality as factory production tolerances create variations in installed heights.

Heads which have had a valve job will generally produce taller installed height equal to the amount of material removed from the valve and seats during machining.

These retainers fit single and some dual springs.

 

Will this kit fit your springs?

 

Use this check list to verify fitment:

1.       If the outer springs ID is between 1.060”-1.070” (measure inside spring, not damper) *For other sizes see note at bottom of page

2.       If the target installed height requirement is around 1.800” or less

4.       If using dual springs, the inner spring ID must be .690” or larger.

 

Retainer size details are listed below. The step(s) on the retainer needs to fit inside the spring.

 

This kit is also available with a installed height of around 1.765"- Use the optional check box towards the top of this page.

 

      Retainer Step sizes:

  • First Step Diameter: 1.060"
  • Second Step Diameter: .690"
  • Retainers and Locks are 7 Degree
  • Parts are identified with "Intake & Exhaust" labels.
