I have a few questions about a new setup that I'm thinking about trying. First does anyone know if you can use the crane 1.8 roller rockers w/the ASA cam and not have any problems? I'm also thinking about having the heads decked 40 thousandths, I'm actually getting a set of heads from a friend that have already been decked 30 and am just replacing the valves w/manly 2.02 and 1.6 valves, and having them take another 10 thousandths off the deck. My main concern is going to be clearance issuses w/the valves and pistons. Any help would be appreciated, and if anymore information is needed please let me know....
