318 /360 head? intake.

hey guys. am building a 318 with 360 heads.
my question /problem is i bought a 360 cast intake 1971 but the ports are different. not the fuel ports but the exhaust one that crosses over intake. the ports are on the head but not on the intake?
thought you could use any intake would work but guess not.
just pics down loaded of net.

see the half circle on head will not be covered by intake man. the gasket is the one to suit intake if that makes any sense.
so what number casting do i need to be the correct one to suit heads. guy bought this off has cpl more so may be able to swap.
thanks for any help.
cast # on manifold 8614025-1 date 11.15.71
heads are 4027596
