Unless your tune is completely jacked up and or you haves some really weird tuning issues, adding headers should NOT damage your engine.
Sure, it will need tuned but, the PCM will or should (if it properly functioning) adapt for the added air flow.
Your LTFTs will normally go POSITIVE and that will make your WOT Power Enrichment (PE) AFRs more rich (RICH is safe) Not good for max power or efficiency but safe
Its always a great idea to data log and figure out what the addition of headers or any mod does to your tune.
I added headers to my 02 Z and my 06 Coupe and drove it untuned for many months. My only issue was crappy fuel mileage and nasty carboned exhaust tips.
Do you need a tune after a header install? Yes. Can you drive safely until you tune it? YES.
