Hard to say about the clearances but the Buick and Chevy share the same exhaust port configuration. I don't know how close the ports are off but with some good fabrication you should be able to change out the flange. Make sure you buy 3/8" thick flanges though, more material to weld to and less chances of warpage. You can find the flanges on ebay, I bought a nice set of 3/8" for $45...shipped.
