Classic Austin Mini Dual Valve Spring Retainer Set

These are the heavy-duty steel retainers for double valve-springs.   Over the years, some of the alloy styles have suffered failures when used with heavy springs at high RPM- They've been known to 'mushroom' contributing to some severe engine damage.  These are the ones we use to build our Stage 1 big-valve aluminum heads, and have proven very durable for heavy springs at streetable RPMs, including when used with the high-lift 1.5:1 ratio rocker sets.
