意大利采购需求：铝压铸件，高性能汽车，铝制汽车零件，气缸盖制造商，发动机零件，OEM供应商

I'm looking for a quote on engine cylinder heads. Can you provide the minimum order quantity, unit price, and total estimate for costs, including shipping to Italy (ZIP 10090)? I can either send a sample for you to replicate or share detailed specs if that's easier. Just a heads up, our heads are similar to a common model but have some differences. Thanks!
