Product Description

 Beehive, .550" Lift for SBC Iron Vortec

Valve Spring Kit for SB Chevy Vortec, Beehive Spring Version, 130 Lb Seat

 High Performance Hydraulic Roller Cams, up to .550" Lift w/ 130 Lbs seat pressure

 

We've been offering drop in valve spring kits for iron Vortec heads for many years now. Just like our other vortec kits, this one does not require machine work when used with higher lift cams.

Over the last decade, beehive springs have grown in popularity, Alex's Parts has you covered for iron vortec head applications.

Of course in the Alex's tradition, our customers expect good quality with a low price, and we've managed to get her done!

Buyers can now order a beehive valve spring kit for around the same price the cam companies get for their beehive springs alone.

Get a set of beehive springs, retainers and locks for your iron Vortec heads for use w/ Hyd Roller with up to .550" Lift.

Manufactured in the USA.

Builders can get the benefits of lightweight retainers/locks for lower reciprocating mass which adds up to increased RPM potential, all for one low price!

The chrome moly retainers are specially machined to produce maximum clearance between the retainer and seal without the need to machine the heads.
 

      Kit Includes:

  • Sixteen- High Performance Beehive Springs
  • Sixteen- 11/32" Chrome Moly Beehive Retainers
  • Sixteen- 7 Degree Hardened Valve Locks

      Optional add on items: (use check boxes towards the top of this page)

  • Hardened Shim Pack w/ .030" and .015" shims, 16 each
  • Premium Viton Valve Seals set w/ seal protector sleeve
  • Installed Height Micrometer for Beehive Springs on Vortec Heads (See: Note 2 towards bottom of page)

 

To save possible down time during installation, we recommend purchasing a shim pack to facilitate setting up the installed heights.

Each kit comes with it's own installed height specification card. Always use the specification card included with your kit.

Using our kit, most heads will provide a minimum of .030" retainer to seal clearance @ .550" lift with most castings offer more. Lifts under .550" naturally will have more retainer to seal clearance.

Additional time is required to build this kit. Please allow 7 days for us to test and batch a matched set of springs (build) and ship.

 

Suitable for most hyd roller cams up to around 244 degrees duration @ .050" This 244 degrees duration @ .050" limit applies to the intake position only, exhaust duration can be higher.

If you need help determining if this is right for your cam, feel free to use the contact us link and we'll be happy to verify compatibility.

 

Requirements- Valve Seal replacement is highly suggested. When changing springs, you'll be all the way into the heads where changing valve seals is easiest. Don't risk having an oil burner when you can update the seals at the same time as the springs. Note- It's important for the installer to verify their seals are fully seated down onto the guide. Seals which are not fully seated will reduce maximum lift capacity.

OE GM Vortec heads normally use: 11/32" X .552" seals. Be aware some aftermarket heads (such as engine-quest) may have different guide diameters. If you have aftermarket iron heads, it is advised to measure the seal provision of the guide before ordering seals. GM castings normally accept our 11/32" X .552" seals.

 

NOTE- Not for Gen III LS series aluminum Vortec. Check our other spring kits for late model Gen 3 applications.

NOTE 1- These spring kits are hand built. This means each kit has springs which were tested and batched to a matched set. Always use the installed height spec included with your kit. It's wise to save the installed height spec card for future reference.

NOTE 2- This is a universal installed height micrometer. It is modified to work on iron vortec heads and comes with a steel ring insert to be used with small OD retainers like beehive type. This tool will work with both, beehive and Std larger OD retainers. This is a good universal tool for engine builders as you only need one tool to use on beehive and Std size retainers.
