|  | Stage 5 Head
You can't outflow this head without going to oversized valves. The Stage 5 head is hot-tanked and pressure-checked, then festooned with swirl-polished and undercut stainless steel valves, with brand new valve guides and valve stem seals. The head is decked and new exhaust manifold studs are included.
The Stage 5 port work is our most aggressive, giving maximum high-end power. Stage 5 heads also get extra care and attention at the valve seals, where special techniques maximize flow.
Manley high-strength valve springs and titanium retainers allow maximum rev capability.
This head has an intake-side flow rating of over 283 CFM!
