Hello : and welcome
yes those are not stock screws, but are ok.
the stock screws are non ISO screws, ISO 6mm use 10mm hex heads
the susuki screws are custom 8mm head screws, and if lost, very hard to get
so all mechanics try ISO screws, then that fails the heads hit the pulley bell. oops
so that leaves allen or torx as good choices, not philips.
------------------end sordid history --------------------------------------------
2 more choices number one tops list
1: leave them alone ! service belt as though they don't exist.
2: or
if it was mine, id take it off. belt off first.
then pulley larg 17mm huge bolt next
then on the bench work it over. (10x more easy here)
first lots of pen oil, and tiny vise grips, can you work then loose.
torch the screw head, very hot and use grips.
method 3>?
drill each head off
and buy a new cog and new hex bolts and this time use antisieze.
the parts are listed here. (the table at bottom of page) the stock bolts 8mm heads took a machined 1/4" drive socket to fit, (modified) i dont recommend stock bolts here.
I'd go torx (6mm)

the new cogs in same list. 12631-86500 for 89/90 8v TBI. G16a
also with heads drilled out, Pop gone
the old bolts can be attacked again in the cog.
