It would seem that the oil would end up in the exhaust port, could that cause a carbon build-up issue? What is the recommended hole size to control the flow of oil?

I'm curious about this as well.

Also, will smaller port SC heads, such as the ones i'm using, allow for an increase low end torque, as in the N/A motor (in comparison to the bigger port 78/79 heads)?
