As above: lots of engines give up on the big end and mains just after a rebuild for head gaskets.

If the heads are to be skimmed, DO ensure that thicker gaskets are used so as to keep the compression ratio as close as possible to original. Failure to do so will lead to bearing failure

ok thanks
it was a reconditioned engine so im not sure of the history on it, i.e. whether head gasket had been done before. how would a mechanic no how thick the gasket will need to be?
is it just the big and main bearings?

generally you work out the comp ratio etc to get gasket thickness. yead main and big ends id replace while its out. i got these

but you'll have to wait till engine split to order them as the cranks are different sizes and they differ from centre and rear thrust.

As above, a decent mechanic can measure the compression ratio for you, or work it out from measurements.
