I have always built my own engines. Course I dont have no 8 second car either but I became a tech in 1974 because I wanted to work on cars for a living and I wanted to learn to do it all not just a parts hanger. It actually amazes me how many techs I know that dont build their own engines. Sure I have to farm out some machine work and because of my bad back I decided to go with having Dwayne Porter work my heads on this eng but I still built the eng. I have no problem admitting when I cant do something anymore and I definetly cant bend over a cyl head for hrs porting them with my back. And Dwayne is a professional head porter so he will definetly do a better job then I could ever do. I was very happy to work with someone as nice as him and I know my heads are right. It does give you some pride doing your own work if you can. Ron
