Thanks rspears and Techinspector1, I've read the information you have provided and I appreciate your time toward this. As for the information on the decking that was a grey area initially for me since how I'm new to the knowledge of engine building. I bought this engine as a short block and purchased the heads from a local performance shop. The guy I bought the short block from told me it was "true deck", I do believe. With that being said, I assume that's anther term for zero deck?
