How Do I Install Heads On Small Block Chevy?
Before start installing, there are a couple of things required to do, such as clean your head and gasket from all the dust and oils with a cotton cloth instead of paper. After cleaning, it is time you place your gasket carefully to its accurate position. Lastly, install the heads on very carefully and take your time; then, you can finally torque and seal them tightly.
Are Aluminum Heads Better Than Iron Casts?
To keep in mind, though, both kinds can damage the engine if it overheats. However, aluminum is easier to install and replace as aluminum heads are light-weighted than iron casts.
But when it comes to providing power, aluminum heads can preserve heat more than iron casts and provide more power to the engine as it has more thermal conductivity than iron casts, so it can dissipate more heat.
Does The Combustion Chamber Size Affect The Compression Ratio?
Yes, it does! The smaller combustion chamber will give you a higher compression ratio, but it can create clearance problems with pistons and valves. And a large combustion chamber will reduce the compression ratio, which will result in cooler burning temperatures, eventually leading to inefficient combustion.
Which SBC Head Is Best, And How Do I Choose?
This depends on your preference, but I believe that if you are choosing a head, mainly look for the one with the best combustion chamber, intake valves, great durability, high-performance rate, exhaust valves, as well as focus on the one that would not cause your engine to fail.
Moreover, one of the best ways to test the heads is to lock them and to make dyno pulls. This will enable you to see which one has the extreme power but not choose the one with the highest power. It will also allow you to see a confined rpm, which would not be a good choice for you. When choosing a head through this test, it is best to see inclusive energy and torque results.
