T3 manifold dimensions

[rippershifter]

Does anyone know where I can find the stock dimensions as far as port size and studs for our manifolds? Found a few on google but want to make sure I have the right one as I am modifing a HE351ve to bolt up with out an adapter and dont have my manifold off yet.

I can't remember if it's the t3 or t4 but one of them that you find on google is just wrong. Whichever it is I corrected it when I saved the picture.

You can also use a gasket from the parts store.

Thanks man, I just wanted to be sure before I started drilling and tapping.

The posted pic is a T3. That's a factory manifold.
