why cant we leave well enough alone?

So I bought a complete running 318 about two weeks cuz it was a good deal, "smoked when started" so I knew it was valve seals. Was cleaninI it up and confirmed it was valve seals so start thinkiI'll just throw seals and gaskets at it and call it good. Now I've got a performer intake, 1 head ported, a chrome dress up kit, and am looking at cams! I really don't need to do this with the limited time I have and other builds to do. I hope some local guy can cough up some dough for a nice motor, but why'd I have to open this can in the first place?!? Half sarcastic rant over
