706 Heads On 6.0 Compression

Does porting heads lower compression? What are 706 heads good for? Are 706 heads better than 243 heads?

Does porting heads lower compression?

It is generally accepted that head porting does not have much of an effect on compression. This is because the process usually only involves enlarging the intake and exhaust runners in order to improve air flow through the engine. However, there are some experienced porters who take it a step further by removing material from inside the combustion chamber for various reasons. When this is done, it can result in lower levels of compression within the engine, as less fuel and air are contained within its space when compared to before it was ported. In any case, such modifications should be considered carefully as they may cause long-term negative effects on performance if done incorrectly or without adequate knowledge of engine internals.

What are 706 heads good for?

Are 706 heads better than 243 heads?

Usually, individuals who run naturally aspirated engines opt for 706 heads over 243 heads. This is due to the fact that the combustion chamber of 706 heads is not as large as that of 243 heads, and thus does not have the tendency to reduce compression ratio and diminish horsepower output. Therefore, these 706 heads are typically preferred by people running engines without forced induction, since they can help maintain high levels of performance while avoiding a decrease in power.

Where do 706 heads crack?

While testing the 5.3L heads, we found that the 799 heads offered significantly more flow than the 706 heads, with an improvement of up to 20 cfm at certain lift points. Although there was only a 2.5cc difference in chamber volume between these two sets of heads, our dyno tests showed no real power increase on the test engine when using the 799s over the 706s. This result indicates that while air flow is important for engine performance, other factors such as compression ratio and valve size can also have a major impact on how much power is generated by an engine build.

How much do 706 heads flow?

To test the performance of two different 5.3L heads, a 706 and 799 head, a modified 5.3L head test was conducted. The results indicated that the 799 heads offered more flow than the 706 heads, with an increase of up to 20 cfm at some lift points. While the chamber volume on these two heads were close in size, only within 2.5 cc's of each other, this did not translate into power according to dyno tests done on our test engine. This outcome shows us that while there can be similarities between similar parts such as these two cylinder heads, they may still perform differently depending on engine configuration and other factors which could have an effect on its performance capabilities.

Do aluminum heads give you more horsepower?

To get the most out of an engine, one needs to ensure that there is a balance between air and fuel in the combustion chamber. Aluminum heads can help to optimize this ratio by dissipating heat faster than other materials. This means that higher compression ratios can be achieved with less risk of detonation, as there will be more efficient cooling of the head. Moreover, cooler air is denser and therefore more power can be produced from it when it is delivered to the combustion chamber. As such, aluminum heads are an ideal choice for getting maximum performance from an engine without compromising on safety or reliability.
