If someone's entertaining the conversion (worth it or not) make sure the machine shop knows what they are doing. I had it done by REX Racing Engines in Sacramento and they ended up raiseing my crank .020 closer to the cam. Chains dont come in .020 so you need a gear drive with smaller idlers. It was a big surprise when my new motor blew in short order, I tore it down and found a sloppy IWIS chain...
Good god, what a nightmare.
