Default '69 GTO LS Swap-What Headers?

Like the title says.. I've swapped in a LS engine using UMI motor mounts into a '69 GTO Convertible and now I need to get the exhaust finished up. Can you recommend a set of headers that will go in without needing massaging, or hammering, or frame cutting?

Car is a power steering car with 4L60E automatic transmission. Thanks in advance for any assistance. I need to order the headers right away so I can get this project finished up. I keep hearing people say the F-body headers by Speedway are the ticket.. I just want to get something that will drop right in with minimum issue.

in my 69 chevelle with lsx innovation motor mount plates i used speed engineering a body swap headers with 1 3/4 primaries and they fit great. i had to dent one of the primaries for my clutch z bar but not bad.
