Nash, I for one love headers, and have never had problems with any of the headers I've put on any of my rides! So don't take it to heart! I really have never known how or why some seem to have problems with headers and some don't... But I never have, and would put quality headers on ever car I have... (ok.. I guess I only have 2 cars right now out of 6 that don't have headers yet! Lol...)

Personally, I have been able to feel hear and see (Longer, twin black racing stripes on the pavement) the performance increase once I changed to header especially on my Pontiacs! Even my curent bird, I have had the headers on and off 3 times, and have never even retightened the bolts... and have never had any problems (actually, just a slight leak right now, but I didn't feel I got the bolts that tight upon replacement as I was in a hurry to meet soem guys for a cruise)

And as for the fit of my super comps? They fit great, better than the headmans I had on my 421 in my 68 bird? I can even get these out and back in in about 1/2 an hour? So maybe they had a couple different designs? Not sure there?

Anyway, use the copper gaskets especially at the collector! And if you are worried about the bolts loosening, get the locking type... And coating... I was lucky to have found someone with a friend that did coating on the side (after hours) and got my Hooker Super Comps coated for $40!!! And I have the relay for the starter (Ask me more about it and I'll send you info) and I've never had any starter problems at all. Nor have I had filter problems... tight getting the filter in and out... but not impossible?

So, get the headers, use a high temp paint (ok) por-15 or manifold paint (Good) or get em coated (best) and get the copper gaskets, and the locking bolts... and just enjoy the sound and the slight performance gain, and just get out there and drive!
