I'm going to install a new header, and at the same time I figured it would be a good idea to replace the old, stock gasket. At San Leandro Honda Parts, they listed 2 different head gaskets, and I was wondering which one to get?
1)18115-PT0-004 GASKET, EX. MANIFOLD (ISHINO)
2)18115-PT0-003 GASKET, EX. MANIFOLD (NIPPON LEAKLESS)
It's #3 in this picture:
Thanks in advance
