hedman "tight tube" hedders?

I'm pretty sure these are the headers I have. I bought them from Summit back in 05'. It looks like there is an interference problem on the passenger side, Though this was originally a slant six car, so maybe it would fit in an original V8 car. I'll try to take pics and show you guys. I do not have exhaust hooked to them yet. Looks like other people are having interference problems.
