It is not just the head you need to worry about but also the effect of the fuel on the epoxy.
I did a similar fill in of port roofs with a steel loaded epoxy in an iron head and the only reason the filler stayed in was because we installed some tiny angled dowels first, the epoxy shrank because of the petrol.
The Loctite website should have the data sheets with chemical resistance data for the epoxy.

Which is why the Moroso product may be the best bet, it's application specific.
