It looks pretty good to me as well, good chamber shape and the plug near the exhaust valve. Maybe the chamber roof is a bit high, it's hard to tell from the photo (I wonder what the alloy one is - that looks good as well!). I'd try a modest skim of the face, maybe 30 or 40 thou just to tickle the compression up. If the whole engine is in bits it may be worth decking the block as well to get the pistons a few thou proud. I'd avoid welding or brazing into cast iron heads, it can be done but cracks very easily - plus there's no obvious 'dead' areas to fill.
