KA Header options.

[Tank_4g63]

Been looking at KA headers, what is the difference between the round port and square port headers?

It looks the stock exhaust manifold has round ports.. I don't understand why this is true if, as I have found with the search function, all KA24des have square ports.

Heck even the gaskets from auto parts stores are round. wtf is up with that.

Im curious as I am also in the market for a header. I'mma gonna yank off the mani this weekend and look at the stocker I got. Do you mind posting a pic of your manifold for comparison sake. The runner entrance ports is all I'm curious in seeing. Been thinking about just smoothing and taking some speed bumps out of the stock one but dont want lose any velocity or open it up too much. Maybe matching it up to the head better.
