will a k&n cold air intake and a 1 inch throttle body spacer have enough clearance without hitting the hood

If your kids or grand kids have any play putty, put a large glob in a plastic bag, place it on the top of the engine where the spacer and air filter come towards the hood. Shut the hood then reopen. Do the measurement. The plastic bag keeps the glob from sticking to anything and giving a false reading. I have an air filter cover on my two carburetors that was fastened with wings nuts. I had to change them to a castle type nut to close the hood. Close fit.
