I have a HS40 engine I want to get a little more torque out of & want to increase the compression. I plan on removing the bump on the backside of the exhaust valve camshaft lobe for full compression but I also want to reduce the head squish a little bit too. I would rather use a thinner head gasket instead of shaving the head down if I can get one. Can someone tell me if a 0.10" head gasket will work without any clearance issues with the valves contacting the head?
