Very true but before putting together a complete engine and then all the trouble of fitting it up etc id still like to know what my bores were like,skirt clearance how oval etc as a leakdown will just show its not knackered but if the bores measure up nice then no worries at all..

All depends how anal you want to be,im sure guys that race etc would just chuck a head on it and rag it to see if its good! lol
