ok guys well I'm just wondering what I should do with my engine. I've noticed lately that the cars is smoking more not all the time but enough for me to notice like on start up which I figured is valve seals. Well here my question when I do the heads came do you think I should put new pistons in it? It's already a 30 over bore so I'm guessing a 40 over bore would be ok. Well which company should I use and should I do the rods too?
