I wouldnt think there was any major differences.. just use the late gasket.. otherwise there would be problems putting alum. heads on the older blocks..

the water passage to the intake IS different, but it should still be sealed by the later intake gasket...
I got rid of my E7's or I could compare them to the 66 289 heads I have..
