LUNATI LS Dual Valve Spring Kit w/ Steel Retainers, .660"
[73925K1]

I'm in the middle of doing H/C and decided to upgrade my valve springs. It was either the PPs or these. These were my main choice due to the price and due to the steet retainers lasting longer and being much stronger over the titanium PP retainers. The weight difference to me is really negligiable.
