I just had a motor put together and I'm getting close being able to start it up. I made a few changes. Raised compression to 9.5:1, 98 cobra cams, egr delete, went from mac 1-5/8 to kooks 1-3/4 headers and 2-1/2 to 3" midpipe. Would it be ok to start the car or should I wait and get a base tune for the changes? What plugs and gap should i use? I've always used ngk tr6's
