Will there be any valve clearance issue if I run a hoca 2.5mm stroker with an a14 cam? I currently have a 180cc stock crank engine.

you should be adding 1.25mm base gasket then
but the best way to check is to turn the engine over by hand with the old head gasket and no spark plug
put a flat bit of Pleistocene, clay or soft wax on top of the piston
maybe an 1/8 inch
and if it doesn't clonk on the valves take it back apart and check the stuff to see if the valves have dented your clay.
you can probably just double up on an ordinary base gasket 2.5mm isn't much almost a tenth of an inch .0984 of which you only have to deal with half
