What are some high-performance valve springs that are recommended for engines with aggressive cam profiles?

In my experience, a good set of valve springs can handle the extra load without giving up on durability or performance. For instance, Supertech Performance has some solid options for high-performance and racing setups. Their springs are made to take on the demands of aggressive cams and high-lift engine valves, which makes them a great pick for custom engine builds. Their dual valve springs, in particular, are designed for high-load situations, and you can check them out on their website: Supertech Performance. If you're working on either a street performance project or a full race engine, it's definitely worth looking into these options to keep everything running smoothly under tough conditions.
