LS1 Header Gasket Question (Port Size)
#1

I’m putting headers on my LS1 for the first time. They’re 1-7/8” and while I wanted to use steel gaskets, they all look like they only match the port size for the stock exhaust manifolds. Should I use the paper gasket supplied with the kit that matches the port size of the headers I got, or will a steel stock gasket work without causing any issues?
