I've heard before from somewhere that you can pick up a little bit of extra power by running 2 exhaust camshafts in the big port, instead of running 1 intake and 1 exhaust cam. I've search but having a hard time finding info on it. Anyone have experience with that or has some info share on the subject?

I have several pairs of large port cams stored away and I have a cylinder head apart right now, figured now would be a good time to do it since I'm in there (again). As long as it's proven to be a beneficial mod.

Thanks.

Both intake and exhaust have the same lift and duration.
