Important: Do not port match your intake manifold to any Fel-Pro gasket as it does not precisely match an AFR head.
Note: Milling head deck will affect flow numbers.
These heads are perimeter bolt only, no option for center bolt. The heads have the 86' and older bolt pattern and the Vortec bolt pattern, but only the 86' and older intakes will work due to the port dimensions. The Vortec is a taller port and won't match.
