there was a topic somewhere on the yz forums. the guy described all the thing just like you did. finally he came to the conclusion that his head was warped. I'm not a specialist, don't treat my post as conviction.
ps: maybe your valves weren't installed properly?

Did you also have the valve guides checked for wear? Just thinking that if the guides are worn out and the valves have any wobble, it may not seat properly and therefore not start.
Backfire through the carb, you are not giving gas while trying to start are you? Remember that the "procedure" must be followed without error to reliably start the bike.
