Best SBC Cast Iron Heads Buying Guide 2021
There is always a chance of getting the wrong cylinder heads for your car. To avoid such situations, you have to check some basic features to make sure you are picking the best SBC aluminum heads for you.
You can not just randomly pick cylinder heads and fit them in your engine. Always check if your selected cylinder bolts are specifically compatible with your car. The first point is to choose between iron or aluminum, as different materials expand and contract at a different rate.
To ensure the best performance of the engine, first, determine which one is best suitable for the engine block.
Intake / Exhaust Port Volumes
Having the big-sized intake port volumes doesn’t always mean they are better for your car. Sometimes the small ones can be more suitable depending on the size of the engine. They generate more low-grade torque and hard throttle response, which is better for street applications.
Due to the extra airflow, the larger ones are more favorable for high-revving engines. Hence, compare the valve size and the stock exhaust port volume, and then choose a quality-flowing exhaust port of the right size.
Combustion Chamber Size
To ensure the optimum efficiency of your car engine, you have to pick the proper-sized combustion chamber to increase the compression fraction. Remember to match the engine components like stroke, bore, head gasket, ring location, and deck clearance.
Before you pick the cylinder heads, you need to determine the main application you want the car engine to use. Road racing, circle track, street driving, and many more require specific types of cylinder heads in the engine. You can also alter the valve lift, duration, airflow, etc. to upgrade the performance level of the car engine.
The price of the cylinder bolts depends on the brand, model, material, etc. You can always buy inexpensive ones to suit your pocket. However, the quality of such tools matters for a safer ride. Hence, if you have enough funding and want your car to perform for a longer time, try to invest in the standard bolts rather than the cheaper ones.
Warranty is an important feature that you don’t want to miss. You wouldn’t want to spend a large sum of money on something that can break overnight. Hence, buy one that comes with a satisfying guarantee and refund system. Nowadays, most manufacturers are providing well-built cylinder heads backed with a warranty.
Aluminum vs. Cast Iron Cylinder Heads
As we all know, cylinder heads can be of two types. While both are useful in their own way, you have to check the fact yourself. Aluminum heads are more on the lighter side, which also comes with a low price-tag compared to the cast iron ones.

- Can handle mild to high-level compression ratios
