I think i asked once ages back but when i type in the search nothing much comes up cause the words are tooo common and the search engine disregards s1,s2,s3 etc

Basically was after any info on the minor difference between the head designs? I have an s7 from my dead 92 motor and i'm pretty certain the ones under the house a s3,s5 etc from various swift and sierra motors i had pulled apart. They are all in the same relative condidion so i am trying to decide if there is anything i should be looking for before rebuilding one.
