75 GP Headers
 

Does anyone make round port headers for 73-77 GP's? Dougs has them for 70-81 Firebird and I know the front frame horn of the 73-77 A-bodys and GP's was based off the Fbody stub but not sure if its close enough to work in a GP chassis.

Thanks, Jay J

I don't really know either. I suspect the F-body headers will fir but ?
You might rry giving Dougs a call as they probably would know better than anybody:confused:

Any updates? 73-77 GP is difficult to find off the shelf headers that fit without a lot of hammer modifications. Even the cheap 3 tube headers require some hammer work.
