I have CPPA's on mine but no p/s. That design was bought by TTI,or so I am told. Schumacher makes a shorty header that looks good but you'll leave some HP on the table...if that's a concern of yours. I don't believe Hedman makes a specific A-body BB header but I know a B-body header can be made to fit Check the tech articles at:

www.bigblockdart.com some good info there.

Guess it all depends on what you want and what you want to spend. Good luck! a lot of fun to be had with a BB A-body
