These worked great with no modifications to the headers. The install involved a little ingenuity on the driver's side after removing the drive shaft. The stock starter doesn't work on the passenger side, but everything else was gold!

After installing raised port (0.300") heads, my old headers would not allow me to thread spark plugs in on two of the holes on the passenger side. Online, I found one person that stated these headers worked with the raised exhaust port heads. They work an allow better clearance for the spark plugs. It did require modification of a spark plug socket by cutting it down to 1.5" overall length and had to drill the socket to allow the spark plug socket to slide over the end of the plug. Now a open ended wrench is needed, but I have spark plugs installed and clearance for plug wires.

Fits great
Bought these headers for a big block swap into my 4th Gen 75 nova. They fit great with so much clearance. Had to trim a bit off of the driver's side motor mount but otherwise fits great.

Look great. Fit like sh t
I spent 4 days trying to make them fit in a g body. I'm sure if I had stock heads without raised exhaust ports they would have fit a little better. That being said they are a nice piece. I can't complain that I put them in something they were not intended for.
