If a YB 200 block has been wire rung/ringed (whatever lol) does this mean the wire needs replacing everytime the head has to come off? Also do you use a standard head gasket??

Any fibrous gasket with a soft metal fire ring is fine

Wire, if correctly installed, will also be fine. Just check its still rounded and not crushed flat anywhere.

Can you just look at the pics below and tell me if the pistons look like standard 4x4 ones and what the numbers mean on the top?

standard pistons and the numbers are the size of the piston widths,so you can tell if its has been oversized.

I don't actually thing the 91.275 number is the size though i suspect it is a Mahle part number?
