Definitely. What good is a car that you can't get plates for? (which reminds me. When i get my engine back together i need to get plates)
Basically, OP, not to answer your question with another question, but ask yourself. "What can I do to get more air in and out of my engine, and what can I to make it flow more easlily into and out of the engine?" In that answer, you will find the answer to your question.
