Update for those interested.
I ordered a set of exhaust manifold gaskets from Toyota, once they are received I will take them to the company and see what they say. They actually design the flange based on the the gasket and open it up to make sure that there is just a straight flow from the heads to the headers and out.

Once they see the manifold gasket and I talk with them some more about what I have received and read on here and other sites I should have a decision from them and if they say yes, I will post up their information and time frame and all that stuff.


I will make every effort to dyno these headers so I can post up #s for those that want #s.

Since I don't work for this company and I don't sit on my thumb all day, I won't be able to pump this out immediately once they are done, but I will try to get this done and I will try to make it as close to the time that I install the headers and will try to get the temps the same so they are comparable.

Bear with me and I will post again with what I find out.
