if you have nothing but time you could fab a plate to bolt up to the water pump and thermostat housing bolts and then you would have no worries about whether the holes are strong enough, lol.
use a gasket to a pattern to make the bracket from or use the thermostat housing itself for a pattern. mark it, drill the bracket holes slightly larger, bolt it on tight. done.
same for the starter mount bracket. some will say just bolt the chain on there, good enough. if you bolt the chain across the 2 bolts usually only one bolt is doing the actual lifting. a bracket bolted on tight ensures both bolts are doing the work so the load is spread out. same theory for the chain that I would use across the manifold bolts. use a couple of bolts with the short chain between them, then the actual lifting chain connects to that in the middle of the chain so BOTH manifold bolts take the load. of course a home made bracket here would also be better but thats a little more time and effort.
