Product Description

Fits Factory Heads, no machining required.

High Lift Valve Spring Kit for SB FORD GT40P

Application: Hydraulic Roller, up to .530" Lift, 135 Lbs Seat Pressure

Fitment: GT40P 302 heads (for GT40 kits, check our other listings)

 

This version is for GT40p heads w/ staggered tip length valves. If your heads have .393"/.393" tip length valves, select the .393"/.393" option towards the top of this page.

Fits GT40p heads without the need for machine work or other modifications.

Designed for mild to moderate high performance hydraulic street roller cams, Vsk7f49-Q5 handles many popular grinds with up to around 230 degrees duration @ .050" and lift of up to .530" @ the valve.

This is a good choice for Ford letter cams and many other cams within a .480"-.530" lift range.

If you need help determining if this kit is right for your project, just send us an e-mail with the cam specs or better yet, the cam brand & part number or a link to the specification page. We'd be happy to verify compatibility or make another suggestion.

Suitable for 1.6 and 1.7 ratio rocker arms as long as the lift does not exceed .530".

Suggestions: Measure spring installed heights- This kit normally requires some shims to obtain the target installed height. 

Buyers can add: Shims and/or Seals by checking the appropriate box up towards the top of this page. These items are added in at slightly discounted prices with reduced shipping rates.

Please note our viton valve seals are premium OE style replacement seals which are far superior to gasket set seals.

 

Note: This item is intended for hyd roller cams. Hyd flat tappet cams normally use a lower seat pressure such as 110 Lbs. Check our other listings for spring kits to suit hyd flat tappet cams.
