Upgrade Kit: Valve Springs, Valve Locks, and Retainers

Your original valve springs have gone soft after 30 years. In fact, they were too soft to start with. That is a big part of why your truck falls on its face. The original springs only gave you clearance to run a 486/520 lift camshaft. This kit will put your spring rate better than it ever was, and it will give you clearance for as much as a 518/545 lift camshaft.
