I use the carbide grinding burrs made for metal. I have a set of 3" and a couple of 6" for deeper spots. I use the cross hatch style (double cut) type most of the time but to remove a lot of material fast I use the single cut style. The "oval egg" shape is pretty useful for most everything but the "ball" style and the "rounded cylinder" style are pretty handy too. You can get them from most any tool seller (Snap On, Matco, etc) or online at industrial places like McMaster-Carr.com. Have fun and wear your safety glasses!
Maybe late for the party but with a straight 6 you don't want an true dual exhaust. Just smack a decent y pipe on there that doesn't choke like this one, and it'll rip!
I did this on my logs for my 331 SBF before replacing with 1 5/8 headers. Flow is flow, doesn’t hurt
I agree! Thanks for watching
Let me know when I can drop off some Buick 455 manifolds for you to work on lol
You got it Charlie!
Thanks! Good information
Interesting look at the exhaust on that old over head cam 6. What tools do you like to use for porting?
