when i did mine on my 240 i took out everything and blocked off the holes with nickles and the original bolts. there are some write ups around some where just search around, check out www.sfl240sx.com, and i think www.zilvia.net
where u located, my cuz has a motor that im sure he will sell for cheap, its either got a Bent valve or spun a bearing, and if ur rebuilding it, it should be fine
somebody correct me if im wrong
it depends on the pistons you install, u can keep the compression the same(or higher or lower) and bore it out.....if u just want more or less compression u dont have to bore it out, just get different pistons
