FAQ
Is this head truly “bolt-on”?Yes—it's assembled and ready to install, but you must follow OEM torque specs/sequence and use a suitable MLS head gasket and clean, flat deck surfaces.
Do I need head studs?For any tune, towing, or boost increase, head studs are strongly recommended to maintain clamping force and prevent gasket issues.
What valve springs are included?The head is assembled with new performance valve springs appropriate for street/working power levels. Higher-RPM or big-boost builds may benefit from 103#+ springs (see Recommended Parts).
Will this work with stock injectors and turbo?Yes. It’s optimized for improved flow and sealing on stock to moderately upgraded fuel/air systems, and scales with larger injectors and turbochargers.
What gasket should I use?Use an MLS head gasket sized to your piston protrusion and deck measurements. We list common 03–07 sets above—match thickness to your build.
