You will notice the difference in the corners and you will need to pay attention to hardware. I have lost engine mount bolts and header bolts before I learned to check everything any time I look at it. I have an early torsion bar suspension and I had to reset the torsion bars after changing to the aluminum block and heads. I have a Shelby block with Dove heads and intake. I have had no problems with the Shelby block and would use it again if I needed another one. I can't say the same for the other stuff.
