So you won't be giving anyone a real world test to go by. I'd bet 99% of people reading about this test will use an out of the box intake if they were to use these heads.

Small heads w/ an expensive great flowing intake versus big heads w/ a crappy flowing intake. I'd like to see how much the bigger heads are worth over the smaller ones w/o having to make an assumption about the difference the intakes make.
