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

Beehive springs have been growing in popularity, we've been asked many times- "When is Alex going to offer drop in vortec kits with beehive springs?"

Of course in the Alex's tradition, our customers expect good quality with a reasonable price- we've got you covered on both!

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

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) 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.
