If you're diving into the world of performance upgrades, the Ford 105E-116E high-performance 'PACALOY' dual valve spring set is a solid choice, especially if you're working with racing camshafts. I've had the chance to use these springs in my own setup, and let me tell you, they really make a difference. Just a heads up, you?ll need to get your cylinder head machined to fit these, and don?t forget to grab the retainer part number RET1600 to complete the package.
What I love about these springs is the way they handle pressure. With an impressive 82lb seat pressure at 1.260", they keep everything tight and responsive, which is crucial when you're pushing your engine to the limit. And if you're worried about coil bind, they?ve got you covered there too?coiling in at .670" means you can really let your engine breathe without worrying about those springs giving out on you.
Whether you're building a Ford, Nissan, or Toyota, the KVS402 Kelford Dual Valve Spring Set is worth considering. These springs are designed to optimize your engine's performance, so you can really feel the difference on the track or the street. Trust me, investing in quality valve springs like these can make all the difference in how your engine performs under pressure.
