The 2-1 is designed for 80-84 models, so they say:wink2:, my '71 has an '80SG plant w/ the '71 BS38's and points ign. The header took some massaging to fit, but it ran from the get go. I eventually went up 1 size on the pilot jets and 2 on the mains. I had K&N pod filters, but also the flat spot up top that comes with them:(. Now have the UNI's. Are you running pods or stock(ish) airboxes?

Plug and play, yes... and no. Leave you wanting more, yes.

BTW sounds great :thumbsup:
 
The stock CV carbs do a pretty good job at compensating for mild mods with just adjusting the pilot screws, maybe 1/2 turn farther out, and possibly (but not nessesarily,) needle clip position unless you go for all out top end. So it should just be some minor mounting issues and spark plug reading to determine proper idle/pilot mixture.
