Doc and Tinker,

Thanks for the replies guys-this board really is amazing.

1. I probably won't be able to "switch out" different shims as the only valves that off spec are too tight-also all on the exhaust side as well as being a fairly uniform .05-.1mm off. I will call around to local dealerships.

2. I will try to take the retainers off evenly. I'm supposing this means loosen them in a pattern a little bit at a time? The manual just says "remove retainers." Its things like this that make me wish I had some basic training...
