    Looking at the Dutra duals and I'm wondering what head pipe connects to these ?

    One your exhaust shop will need to fabricate for them. There's nothing ready made

    If you got a USA Dutra manifold(s), check the head flange underside for a clearance step. Seems a few blocks interfere with the original USA casting? Also check the exhaust port shape thickness for the triangle washer seats, some had grind to fit 'observations' and exhaust flange for interference issues with some other part. This was from the Aussiespeed site trumpeting their Aussie cast version. Just want to know the fitment quality of the USA vs. the 'new' Oz castings.

    Those are correct statements. Also the number one runner could be blocked with a thin layer of cast iron. Easy to knockout with a screw driver. The rear manifold would hit the battery stud on the commonly used late '90 Dakota mini starter from the 5.2. The manifold needs to be ground down there.

    They were not bolt on and go. But they work very well. Doug once said there was .10 difference from headers.
