COMP Cams GT40 valve spring kit is a complete drop-in set for Ford GT40 and GT40P cylinder heads, developed for flat tappet cams and up to .570" lift. The package contains springs and locks sized to handle aggressive lobe profiles without machining, plus Viton valve stem seals. It’s intended to make valve train upgrades straightforward by fitting directly on stock GT40/GT40P heads and supporting higher spring rates and lift for more demanding camshafts.
