Sure smells like exhaust fumes, I've re- checked (a few times) fuel leaks on the manifold which were there when first setting up the engine but I believe that problem has been solved. As far as a poor seal on the headers I did use the "crushable " gaskets although not the extra bottom bolt. I'll be under the car soon as it's time for an oil change , of course there's an oil leak or two and I can see where it's been on the exhaust, the smell is more exhaust than oil burning off hot pipes. With the top down/off fumes are not a problem. After the oil change and I get the top back on a trip to the exhaust shop appears to be on the schedule.
Thanks again for the tips and ideas to help track this issue down.
