Intake question?

Dont resurface it, do as advised. you can also take some RTV and paint it into the water ports to suspend further erosion. If you lay the intake with no gaskets onto the motor are your ports lined up or are the under the head ports? Most of the time the ports are too high with gaskets . If they match up, you could theoretically measure the compressed height of the gasket and mill the intake that number, but that is far more expensive than a tube of RTV.
