Hi. I'm soon going to be rebuilding a 318 and so far have a couple of questions. The plate that fits between the oil filter and block sits too high, the centre boss holds it off the gasket. Are there different versions of this plate? (68 block for RHD, English/Australian version). I have pre owned ductile iron 273 adjustable rockers, they don't have a lock nut. Are they OK like that? does anyone do a lock nut conversion? TIA. Tig.
