Re: Machinist's advice sought
Verne, FIX THE HEAD! Weld up the crack or you're just asking for trouble down the road. It's not a big deal. BUT send it to the best head guy you can find, maybe Dave Mills will help???
Piston is an easy fix. Take it out and get it checked for cracks. IF NONE FOUND, just sand off the sharp edges with a dremel or similar tool and re-use the piston. Deburr any and all sharp edges and you will be fine as long as the gouges are not too deep. But being a 409 there should be a ton of meat there.
Good luck, John
