The 17049 is what I use, the same gasket auto part number I believe is 1067. It is designed for parallel cooling, as is your block and heads. You could run the 1057 as well if the only difference is one hole at the end, but that extra hole for series cooling is not necessary.

That's for a Brodix big Duke head. The Cometic for a standard, conventional BB Chev head on a Dart block is the C5331-(thickness)
