Hi Mike.

Getting your valves out isn't very difficult actually.
You need to disassemble the small cover beneath you exhaust manifold, take off your carb first!! ( taking off your exhaust manifold also will make your job easier, but you do run the risk having to replace the exhaust gasket! ).
Behind the cover you'll find your pushrods, valvesprings and valvestems.
The springs are held in place by a small pin thru the lower side of the valve. Look closely, you'll see the pin inside the springseat. Now you have to figure out a way to get the spring tension off the valve in order to get out the pin.
I have adjusted a clamp for my own use ( as used in wood construction )to fit under the springseat without blocking the pin and by screwing it up releasing the spring tension, this way you can remove the pin. And now your valve can be removed.
You have to construct such a clamp or find someone who has a valvespring clamp himself.
Always check your valve clearance when reinstalling!!
Adjusting your valve clearance can be done by grinding the end of the valvestem. Keep in mind that the pushrods wears at the contactpoint with the valve. When the pushrod has worn in you will get false results when measuring your clearance.
Reinstalling your valves is easy, do the steps i descibed in reverse order!
The pin locking your valve and spring has to fit inside the springseat, and should not be sticking out.

Using common sense will get your job done easily.

Good luck!

Regards Jack
