wow, well spotted!
one of my 4Ks (engine number beginning 00, i assume its an early one) has no ribs, this has previously been 40 thou with a bigport. it came to me with a blown head gasket tho i think from heat (dark chocolate colored bores)
the other 4k (engine number beginning 903, i have access to the vehicle its orignally from, i will check date) has the sydney harbor bridge between the casting plugs like my 3k does
thanks heaps for the tip man!!!
