OK. Here are the pictures. It is obvious that I wasn't nuts... the springs ARE different. It's no wonder that we had spring problems. The difference is approximately 1/4 inch. Sorry I don't own any micrometer tools, just a worn out tape measure (non-metric).
The distance from the keeper to the valve face was different on the intake vs exhaust valves also. The keeper on the old intake was lower (more distant from the valve face) than the keeper on the exhaust. The keeper notches on the old valves were different depending on whether they were intake or exhaust (see pictures below).
The new valves used the same keeper notch and distance on both intake and exhaust and, of course, the same length spring.
