'70 or '73 318LA Which to rebuild?

We had a GIGANTIC controversy on here one day where someone accused me of lying. I don't take such comments lightly. "The thing is" some blocks have blind head bolts and some don't which may or may not indicate stronger blocks

If you want much power have them sonic checked for cylinder wall thickness
