My BBK shorty headers have a lot of extra weld material in the ports. Enough where it looks like it causes some restriction. Would I gain anything by trying to smooth this out or is it just a waste of time on headers?
Here is a test to say it will not make a difference but if you have the time and the tools it definately will not hurt.[/QUOTE]
I've seen that video before, they really had to beat on them to get and change on the dyno. Think I'm going to smooth out the really bad spots and call it good.

If it was flying at Mach 3, I would get worried and do some smoothing. Since it isn't moving anywhere near that fast, it is whatever makes you feel good.
An air powered die grinder (less than $30 at Harbor Freight) and another $30 spent on a 1/2" diameter carbide rotary file will do the job. If you don't have a good 40 gallon tank or larger air compressor, or the $60 for the proper tools, forget about it. A Dremel tool or electric drill just isn't up to the job.
