I would like to know if someone can please tell me how to tell if I have BB headers??????
I was told they look the same as SB but they are slightly taller for floor clearance!!!!!!!

Can someone please help, and thanks in advance!!!!!

 

By the way, i have a 68 cutlass!!!!
Thanks again!!!

 

Any measurements I can go by?????

 

Unfortunately, no. Every header manufacturer builds headers that are slightly different, so there really is no magic measurement you can use. Either they fit or they don't, unless you can find a stamped number on them someplace. Inspect the header flanges very closely for a part number.

 

Thanks for the response Joe!!!!!
I don't know what brand they are but they do have 030 stamped on them if that helps any!!!!!!!

 

Post pictures of both headers,, especially close-ups of the flange. Someone might recognize them.
