Here are the new intake valves (left, next to the springs), some of my old valves (center), and new exhaust valves (right). The intake valves are a bit larger than the exhaust valves, and the piston cutouts for the valves are different sized. Yet, some shops manage to get pistons in backwards occasionally.
The new seats and guides have already been installed in the heads.
Next, Gary will test the springs to see if they are in good condition. I expect they will be, since the car only has 25,000 miles on it and the springs have been sitting in a box, uncompressed, for 20 years. These are not my springs and valves, but this is the instrument that Gary uses to check the compression curve on each of 48 springs.
