Product Description

PAC Racing 1520 Beehive Valve Spring Kit - (#BB2)

This PAC Racing valve spring kit is designed for most big block style cylinder heads with hydraulic roller and hydraulic flat tappet camshaft profiles. This is a replacement for the large and heavy dual springs that most big block heads come equipped with. Some OEM cylinder heads require the spring pockets to be machined to spring locator fitmant.

155# at 1.880" Installed Height
377# at 1.280" Open pressure

NOTE: Verification of all spring pocket and installed height parameters is required.

2) Choose your valve seal diameter: .500" or .531" guide top

3) Choose your valve guide diameter: .500" or .563" guide base
