I had experience in the past with grinding off the guides flush.
I have to say I wouldn't do it again, my main concern is if there is any 'wobble' on the inlet valve thet it may crack the seat, that's what happend to me, yes different engine but all the same. Also I agree about the heat transfer on exhaust side.
I have no doubt that flushed you will get more power, but the trade-off is not realy worth it, esp. if you are on a budget and planning to do it only once.
I say this to HELP, please ignore if you like.
