Having the equipment helps alot if you are smart enough to do the work yourself. I was taught in the early 70's in auto eng rebuilding class I took how to grind valves and seats and knurl guides and pistons and so on. So I am very lucky my brother has his own machine shop and we can do almost all of the work in house. We can even bore blocks but we cant deck blocks or cut heads. I took auto shop to learn and be a tech who actually does all the work and not farm any out unless I have no choice. Its always more pleasing to do your own work if you can but I do agree if its over your head to let someone who knows how to do it right do the job. I have also learned over the years no matter how smart you think you are you can always learn more from anyone and never be afraid to ask questions if you dont know. You have to use common sense even when building your eng. Ron
