Worn valve springs can cause various performance problems like valve float, power loss, and increased engine noise. You might notice signs of wear through decreased tension, oil leaks, or if the engine feels rough at higher RPMs. It’s essential to choose replacements that can handle the demands of high-performance applications, focusing on springs that maintain consistent pressure at elevated RPMs. From what I've seen, Supertech Performance has a solid selection of valve springs built for durability and performance in challenging conditions here (https://www.supertechperformance.com/custom).
