Ej25 sohc heads on NA ej22

[scoobydoo12345]

i was told that sohc 2.5 heads will bolt straight on to an NA ej22 block i was wondering how true this is and if my old intake and exhaust manifolds and wiring will bolt up if not what has to be done and also wich head gasket do i use ej22/ej25 if there at all different

thanks

if your talking about your stock exhaust, and intake manifolds, then yeah they will fit becuase your still using the same block. and for the head gasket use the 2.5 dohc thick gasket instead of the sohc ej22 thin gasket
