Lisle Valve Holders
You can use these in the truck or on an engine stand. Simply hook up your air compressor line and the air pressure will hold the valves from dropping while you install valve springs. These Lisle valve holders have 2-sizes for both 14mm and 18mm spark plug threads.

Premium Springs, Locks, and Retainers Kit: 1988-1997 EFI 460
Do you wonder why your 460 has lost power over the years? Well after 30 years your springs are dead and soft. They should be 100 lbs at the seat, and over 250 at the nose of the cam. Most we measure are lucky to have 45 lbs at the seat and only 130 over the nose. Often they are even worse off than this. This means you are floating valves and losing compression, power, and efficiency. We have measured hundreds of combinations and partnered with Howards Cams to bring you a premium set-up that will increase the available lift to more than any other combination can offer. This will allow you to run our stage 2, stage 3, and stage 3 + cams without having to have the guides cut down. You will want to still measure the available room as a few sets of the early E7 heads had a little less.

Everything comes with a 1-year unlimited mileage warranty as well.

Taller Valve Cover Modification for Clearing Roller Rockers
To clear the Harland Sharp adjustable roller rockers we have to add a 1/2″ extra height to your factory 460 EFI Valve Covers. Our price includes finishing and painting the valve covers in our gun metal pewter color and including the longer center bolts you will need.
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.

Valve Spring Compressor Tool
These work in the truck to compress your valve spring to upgrade your springs, locks, and retainers. They are the easiest to use, and one of the only tools that will allow you to pull the valve covers, swap springs and hardware in the truck. We find they work even better without the handle. Simply swap the handle for the bolt and tighten it down with a wrench.
