How much would be left on the table?

Holy crap! I didn't even consider the mismatch from the port differences. Looks like I may be looking for W2 headers, or la headers and some W2 flanges. Thanks for pointing that out! I think it would be a waste to put W2 flanges on the small headers haha. If I'm gonna do it, I might as well do it right. I guess. LOL
