Tom,

Your post reminds me that in race applications, which then might extrapolate to high performance street engines with similar characteristics, when you refresh your engine, the valve springs get replaced. When I brought my engine to Donahue Brothers it was not even a question on their mind, and the engine had 8 race weekends on it which is not a lot of hours and less than 500 miles, no matter what the springs look like they get replaced as sooner or later they will fail.

Prior to getting my MGB race car I was looking at an early 2000's Mustang race car that had been sitting for a couple of years, and even though it had been refreshed a couple of races before getting retired, the owner said that I should replace the valve springs as the valves that were open had been sitting under high tension for a few years and were bound to fail.

As Gary (Gaz64) said, put them all in the trash and get new ones. Hopefully no serious damage to the head, piston or block. Good luck.

Jim
