4. Cost-effective: Compared to other aftermarket exhaust options, a new manifold can be a cost-effective way to upgrade your exhaust system.

Cons:

1. Weight: Cast iron is a heavy material, which can add weight to your exhaust system. This may not be a concern for some, but it could be a consideration for those looking to reduce weight.

2. Installation: Installing a new exhaust manifold can be a complex and time-consuming process. It may require specialized tools and knowledge, and there is a risk of damaging other components during installation.

3. Cost: While a new manifold may be less expensive than other exhaust upgrades, it can still be a significant investment.

4. Limited compatibility: The Dayton 674-860 is designed for specific engine models and may not be compatible with all vehicles.

Conclusion:

The Dayton 674-860 cast iron exhaust manifold offers several benefits, including improved performance, durability, and better fit and finish. However, it also comes with some drawbacks, such as weight, installation complexity, cost, and limited compatibility.
