I mean the gasket looked perfect, no sign it may have been leaking.
I put a thin line around all the ports on both sides of gasket.
BTW I found out 2 quick ways to detect intake gasket leak.

1. spray a small shot of carb cleaner in oil filler neck, if idle speed increases, bad gasket.

2. Hold your hant over throttle body, allowing air through your fingers, if idle speed increases, bad gasket.
