Will this bolt directly onto my engine without adapters?

Yes. This manifold uses the factory bolt pattern and mounts at OEM locations — no adapters or drilling needed. Install with your existing gasket and fasteners.

Do I need to clean or prep the mating surface before installation?

Absolutely. Scrape off all old gasket material and carbon buildup from both the engine block and manifold mounting face. Use a gasket scraper and wire brush, then wipe clean with a shop rag. A clean surface ensures a proper seal.
