I have a set of G3 ported Eddy heads, and I just scored a mint 400 block, and a set of new Hedman fenderwll headers, and I am just finishing the install of my 605 Hemi in the Cuda....
Those pieces should fit together nicely
I like options, and have three cars right now....When you race, you have to have spares, even if they don't all match.
