My advice would be to look at some of the threads in this section. There are lots of pictures of many different types of intakes. They will give you a general idea of what you should be doing. Study them and try to replicate. There are some very knowledgable professionals on this board also. If you don't understand something, ask specifically about it. Most of them are gracious enough to give you advice.
