I've heard people talk about advancing their timing. How is this done? I'm talking SOHC now, without adjustable cam gears(f22b1). Do you screw with the distributor to do this? Is it even worth it with a stock cam? I'm just curious, because I'm doing a head gasket on my 95 EX and I guess now would be the time to make any adjustments if they would provide gains. Thanks guys.
