Important:
Do not port match you intake manifold to any Fel-Pro gasket as it does not precisely match AFR heads.
Do not use your AFR gasket as a template to port match your intake manifold as one AFR gasket is used for many AFR runner volumes.

Note:
1" longer head bolts needed on four bottom exhaust bolt holes.
Milling head deck will affect flow numbers. Angle mills might require a .120 thick intake gasket.
