Which exhaust gasket?

I'm about to swap out the headers on my car. I'm going to be putting SLP 1-3/4" headers on aluminum L98 heads with D-shaped exhaust ports. I've decided to go with Percy's Dead-Soft Aluminum gaskets. My question is, which one do I use. The 66011 is listed as "SB-Chevy Round". The 66031 is listed as "SB-Chevy D-PORT LT1". Which do you recommend?

This isn't a matter of recommendation, it's what will only work. Get the square (D port) kind.
