Today I started to unhook My motor for rebuilding. I am rebuildding a 327, 1968. I would like to hear some dos and don,ts about rebuilding a small block. And thier are some issues that I have. Issue 1. Are small block heads the same as far as how they fit on the motor? Issue 2. Is it better to use headders rather than stock exhast manofoils for the street? Is it better to use HEI rather than a point system for Street. How important is a PVC? What,s a good way to brake in a motor? Is there a way to tell what kind of car a intake manofoil comes off of? A lot of questuions, I know,LOL. But I,ll have a few more I,m sure. Thanks, John.
