D-port heads with with round headers
I have an LT1 engine and it has D-Port heads, similar to the zz4. I bought OBX Headers with 1 7/8 primaries. They are round, but big enough to cover the entire exhaust port. So I just wondering, do I use D-port or round gaskets?

That's a good question. These are a knock off of the Hooker sidemount headers, and the Hookers use the large primaries too. Mabye since the collector is outside and in plain view they beefed it up to look good. I know it's not ideal, but you sacrifice some power for the cool factor.
