Over the holiday break, I've been working in my garage - removing the 360 engine in my 1970 Duster. At this point in the process, I'm attempting to remove the headers from the engine. However, there and two bolts on the right hand side that are in contact with the header tubing. I have not started on the left hand side yet, but looks like a similar condition. Just wanted to see if anyone has dealt with this condition and what steps you took to resolve. After spending some time on it, I thought about bring out a cutting device. However, I wanted to seek assistance from the Mopar Forum before moving forward. Below is a pic of the front of the right header. There is a similar condition at the rear port of the header too (and LHS too).
Thank you in advance for your assistance and Happy Holidays!!!

Can you get an open end wrench on that bolt & move it a fraction of a turn at a time before you reposition the wrench? Loosening all the other bolts then seeing if you can tap the header rearward to gain a hair more of clearance between bolt & tube might help you unscrew that bolt. Also unscrew the bolt then tighten it back up (just snug) then loosen it even further. EDIT you will need to move the flange out as you unscrew the bolt. Have all the other bolts out so the flange can move as you work on the 2 problem bolts, unbolted at the collector also so the header is (almost) free

I was thinking replacing two of the other on bolts on each end, with longer bolts or even studs so the header has something to ride on. This way you wont have to hold the header as you go. Then do as above open end wrench and keep moving it further out till the trouble bolts are free. Then the two longer bolts should be a breeze.

Can you cut off the bolt head and then remove them with vise grips, once the header is out?

Thank you very much to all for the input. I was able to remove all the bolts yesterday based on your feedback. I just wanted to make sure that I was not damaging anything when I initially started the removal process. I'm not sure at this point if I will install headers or stock exhaust manifolds on the 340 engine that I plan to install. However, if I do consider going with headers I will be looking at the bolt position relative to the tubing. Sounds like TTI headers may be the way to go.
Happy New Year and thanks again!

If you put those headers back in those 2 bolts are the FIRST 2 to go back in, you should be able to just spin them in with your fingers as long as all the threads are clean .
