Exhaust Manifold Porting

[ringman]

I have a 12.0@113 GN, since that time I have added new trans w/transbrake, fmic, bigger turbo, and a few other things. Anyways, I'm going to have the exhaust manifolds off this winter, is it worth my time to port these. If so, do I just gasket match them? What kind of hp or et times could be gained?
Thanks

Short answer is: NO

Get way into the 10s, then you can worry about it. Spend your time and money somewhere else. HTH
