I am working on a 67 coupe 289ci with cam, edelbrock perf. intake and headers, and a 4bbl holley, my question is, should i use studs or bolts for mounting?

 

i've never seen bolts in this place. I'd prefer studs there just for the simplicity. when you have the studs in there you pop the carb in and then you know it's sitting right. Further you might have problems getting the bolts in when they're long.

 

yup, and you don't have to worry about stripping or ripping the threads out of the aluminum intake when you use studs.
