The precision CNC machined grade 5 titanium retainers are optimized for mass and stress levels using finite element analysis and packaged for maximum clearance to the valve stem seals. Any OEM replacement or smaller diameter valve seals can be used and clearance to the retainer is about 14mm.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn higher boost drag racing applications these springs can be shimmed for increased seat pressure. The limiting factor in the 4G63 valvetrain is typically boost levels, not RPM. To protect against this, we recommend targeting seat pressure at about 1.7x your absolute manifold pressure (boost + 14.7psi).
