I got some EA81 heads done at Lonsdale Engine works, they were machined and vacuum tested for about $200. Dunno where you live, Lonsdale is a long way to go if you live up north.
Alternatively (if you don't mind spending the money) want to hand your engine over to someone and pick it up completed, drop it off to Steve at Rising Sun and you'll get a brand new looking engine back at the end. I had an engine done there that got new pistons, bores machined, bearings ground oversize, re-faced lifters everything you'd expect in a full rebuild for $2200. He's up at Gepps cross. You might not be looking to spend that much, but think of your factory-condition car with a brand new engine
