Well, the first thing one needs to consider is what one is going to do with it, realistically. Not what one dreams about or would like to do with it, but will do with it. All too often, some will go out and buy the best and most radical hardware. Cams with high lift and long durations for top end, and then cruise low to mid RPM at best, except the occasional burnout on low grade pump gas. An engine is an air pump, top and lower ends and is built by components that compliment each other(s). Balancing an engine isn't inexpensive, but its one of the most straight forward horse power increases one can do. That "unknown" intake needs to match that "unknown" carb or injection needs to match that cam needs to match the scavaging of exhaust, and all of that needs to match gearing and timing. Port polishing? Of course thats good, but not so cheap either, and unless are going to keep it up and clean, fuel deposites from lousy pump gas are going to take a nasty toll on flow real quick. And if you are going to polish those runners and stuff, don't forget to grind them to match where they meet. Can go on endlessly, and there's only one simple solution... a component system built around your needs, your real needs. The most expensive items are not always the best, and are often the worst if they don't match or compliment the rest.

I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
