Has anyone used or looked at these factory exhaust manifolds for a H-body swap https://mechanicfaq.com/ls3-intake-manifold/ ?
They look like they might fit without modification, have no EGR ports and a better looking shape (flow) than the '98 LS1 manifolds.
The 2010-2013 manifolds are similar in shape to the Hooker cast iron swap manifolds.
If no one can confirm their fit, I will likely look for a set of '98s.
