Hey Dan, I don't understand the terms deck and 15proud completely, sorry I'm from south africa, I thought of skimming the head but I don't want to take off to much there. I want to put in a high lifting cam, maybe a kent fr 32, which is a really fast road cam, can I scheme the block an how much can I bore either on the 202 or 205 block? Thank you so much for you're help
