Speed Engineering Race Version Headers Now Available!!
if you have means to do so, not a bad idea to check ANY header or manifold flange for straightness. I own an 18" wet stone I used for guitar neck fret flattening that would be great for this use. A scrap of thick countertop granite with stick on sandpaper makes a great straightening tool. Granite fabricators generally have scraps.
Any large lumps on inside or spatter can be cleaned up with double carbide burr bits easily. If you're just removing large protrusions, you shouldn,t be weakening anything.
PS, no one ever commented on a question I asked::::: Is there any proven way to keep some shine on stainless headers in use???
And thank you demonspeed for turning me on to speed engineering.

So it looks like the OD varies a a bit. I checked em all over, most measurements were a little bigger than 1.75, some were slightly under. Nothing I am concerned with. Again, very happy. Just wanted to throw these up for a couple of nerds like me who want and need actual measurements.

Still beats paying $500 to over 1,000. Just my .02 cents.
