Porting manifold

[gripo]

I have cracked on a bit this weekend and have decided I am going to give the exhaust manifold a bit of tidy up. I know its a crap design but I reckon it needs as much help as it can get.

Is there such a thing as a flexy dremmel attachment that can be put down to port inside it?

One day it will have a custom manifold on it!! One day!!!!!!! when im 100!

Turbo all together and ready to go.
