Product Description

 Beehive, .550" Lift for SBC Iron Vortec

Valve Spring Kit for SB Chevy Vortec, Beehive Spring Version, 135 Lb Seat

 High Performance Hydraulic Roller Cams, up to .550" Lift w/ 135 Lbs seat pressure


Alex's Parts has offered drop in valve spring kits for iron Vortec heads for many years now. Just like our other vortec kits, this one does not require any machine work and is generally good to .550" lift at the valve.

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

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

The springs are made using premium grade multi arc "ovate" wire and are manufactured here in the USA. (PAC)

Builders can get the benefits of lower reciprocating weights and improved spring stability, all for one low price!

Our chrome moly retainers are specially designed for maximum clearance between the retainer and seal without the need to machine the heads.

Requirements- Valve Seal replacement is highly recommended. 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) have different guide diameters. If you have aftermarket iron heads, it is advised to measure the guide before ordering seals.


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