Well Panic, opinions are like a certain orifice on the human torso, everybody has one. I personally have seen too many engines that didn’t perform up to expectations because the owner tried to save a buck. Replacing valve seats in engines today for a qualified auto machine shop is as common a practice as replacing guides.
Larry Carley wrote this article for Engine Builders Magazine on the subject of valve seat replacement, some people may find it interesting:
http://www.enginebuildermag.com/Article/1946/valve_seat_installation_procedures.aspx I didn’t think it was all that expensive when you figure all of the work they did on my hard for $450. After all, I got another 32 years to go so I shouldn’t have any problem getting another 50K on the old gal.
Nothing wrong with your solution but remember, “there are more ways of killing a cat than choking it with cream“.
