turboex

there are 2 types and we have an oringed block. so we ordered the stco cometic gasket that is just thicker. But when we got it there was like an o-ring setup inside it. So we called layy (too) and tried to order again, and he sent us to more of the same thing. See the inner piece has a cutout part added that looks like the layout fo the cyls. Do they make one that the center is just one piece?
