Frequently Asked Questions (FAQs)
1. Will new cylinder heads increase horsepower?
While new cylinder heads can potentially increase horsepower, the results vary depending on the original state of the cylinder head and the quality of workmanship. It is not a linear process, and the increase in horsepower can range from 10 to over 50bhp with a port and polish.
2. What is the best material for engine heads?
For a street engine, cast iron heads are commonly used as they help the engine reach operating temperature quickly after a cold start, which is beneficial for emissions and cold drivability. Cast iron heads also retain more heat, improving fuel economy and thermal efficiency.
3. Can you rebuild an engine head?
Yes, engine heads can be rebuilt. The process involves fixing broken components such as springs, valves, injector sleeves, or guides. Cracks in the cylinder head can be welded to restore its functionality.
4. Are aluminum heads better than steel heads?
The choice between aluminum and steel heads depends on the specific engine and its requirements. For a low compression street engine (9.5:1 or less), iron heads can offer durability and performance at a lower cost. However, for maximum power and if the budget allows, aluminum heads can be a preferred option.
5. Why are Vortec heads so good?
Vortec heads are highly regarded due to their superior design. They have high velocity, minimal turbulence, and an efficient combustion chamber design. These factors contribute to better performance, especially at lift levels below .400-inch, where Vortec heads outperform many other options.
6. Is it worth rebuilding a blown engine?
Rebuilding a blown engine is generally not recommended unless the engine is relatively new and only requires a few specific parts to be replaced. If the engine is worn out or has suffered significant damage, such as from oil loss, it is often more cost-effective to purchase a fully remanufactured engine.
