302 heads

ktcnn94; From what it sounds like what you want, you will be very happy with a set of 302s. I have run them on a stock 318 with a cam(headers, x-pipe, 4 barrel...) and it ran really good.
I do however agree don't put bigger valves in them. No need. They will be good for decent power without and that costs too much. Do a valve job, maybe a mill to clean the up, the self pocket port and run them with a decent cam, and thin head gaskets(Like said). Then in the future get a better set of heads like the LAX, if you want to make 400hp.
