I really appreciate the replies. I have 2 1/2 inch exhaust with dynomax mufflers. Do think I should replace the 2.06 intake 1.77 exhaust valves with 2.19 and 1.88? I have heard that I may lose some bottom end. Do you think that these camshafts are suitable? I plan on getting the compression around 10 to 1. YOU GUYS ARE LIFESAVERS!!! THANKS FOR THE REPLIES.
