LOL even a slant six guy can do it. Did it that way since I was 19 and that was a long time ago. Did it that way at the dealers on a major tune up through the 70's. We are talking stock interference adjusters, not adjusters with lock nuts. Yours and my idea of a "decent engine" is probably different. Six of one half a dozen of the other. Do it any way you want, no need for negative comments or trying to puff yourself up.
