That trucks gorgeous.

Hey toyo guys, lol! Quick question, I would be getting a new head gasket installed in my 88 toyota 4runner 22re and I am interested in just getting a new head as well. Now, if I would like to add more power to the truck I was told to get a different camshaft, is that right??? If so, do you know which one, the size and where I should get it from? I am getting a used head, no need to shave for $150 and looks really clean and in good shape just out of the machine shop for cleaning. What do you think or suggest? Thank you!
