I'm sure there is loads of second hand forged pistons and rods lying around for sale.. New genuine head gasket kit, a proper steel head gasket, bearings, genuine engine seal kit, new oil pump, new water pump, timing belt kit, block chemically cleaned, decked, rebored, head skimmed, three angle valve grind, new dizzy, new rotor arm, new leads, new plugs, get it all balanced list goes on if you want it done right and that not even including the rods and pistons.
