360 heads on a 318, I know it has been beat to death...

Ok, so lets try it again.

I should get the heads milled .30, new valves (1.88/1.60 ), new springs, new guides and new seats.

Will I be able to use the stock pushrods? And will I need to have my intake milled at all?

Just questions that are coming to mind the more I read about this process. Sometimes, I think I should not read so much!
