FAQ

Will this valve fit a Hemi head?

No. This valve is specifically designed for Wedge (Non-Hemi) heads and is not compatible with Hemi-style cylinder heads.


Can I use this valve with stock retainers?

No. The tip is undercut to 6mm, which requires EC 6mm billet titanium retainers. It will not properly seat with stock retainers.


Do I need to modify my valve guides?

No. This valve features a 6.5mm stem, which fits directly into the stock valve guides of big block GX390/Clone Wedge heads.


Why is this valve +.100" longer?

The extra length improves valvetrain geometry for performance applications, especially when using milled heads, aftermarket camshafts, or dual springs.
