V12 Exhaust Manifold Porting
#1
![Default](/forum/images/icons/icon1.gif)
I am going to port and polish the inside of my v12 exhaust manifolds, prior to getting them ceramic coated. I want to do this prior to my 6.0 going into my convert. At this point I am going to smooth out all of the rough casting surface and open up the output portion, as it is a tad bit smaller than the actual opening going into the downpipes. The inlets look to be the correct size, the gasket just needs to be opened up a little bit.
Anybody have any previous experience or recommendations. I know Alan Scott's TWR book stated that porting the manifolds produced some sizeable gains, but they ended up cutting them open and welding them back together, and he doesn't go into much detail. I only plan on doing work that I can reach into, I will not be welding any cast iron here.
Thanks!!
