Porting the head was really worth the time and effort! It idles the same, haven't lost power in any RPM range(it didn't have power in any RPM range!) and it actually accelerates when you step on the gas. It even sounds nice when you do so. Even when driving normally you don't have to press the gas pedal as much to get moving. Just letting people know that these cars aren't hopeless. It could use a bigger exhaust pipe for more improvement, but this is really good for no other mods!
