i ran my 93 wrx for about 4 years with no remap at least 3 dyno runs within that 4 years and it was fine
Porting headers shouldn't cause any problems as ,with the decat, you're just making the exhaust gases escape quicker adding spool up,if in doubt put it on a rolling road to check the fuelling etc
