Headers and Starters on 1969 BB engines

[69BB396]

Hi gents, 69 BB, Hooker comp headers, Tuff Stuff mini starter:

Headers fit fine, but rear pipe touches the starter housing. I can't rotate towards the block or the solenoid contacts it.
Do I have this starter on upside down? Can I flip this over - and will the housing clear? Any experience with this would help. I have an inquiry in to both companies, waiting for a response.
I'll buy another starter if necessary.......

Cheers,
Ron
