if you've got the motor apart you may as well replace the pistons and rings for peace of mind.

as your in OZ i cant recommend anyone do check the bores on the block; but you may get away with a hone or it might be a rebore. the rods will probably be OK; just get the checked for straightness

just get someone decent to do it for you

are you rebuilding to standard spec or are you going for more power?

i have a few manuals i can send you if you give me your email address? it will certainly help with the rebuild
