No. Wait a minute. IF stuck valve only then only remove valve cover on side of block. Mite have to remove manifolds.

But FIRST get a spark plug and knock the guts out of it. Attach a rubber hose. Use lung power to blow into the cylinder at TDC and listen for WHERE the air is escaping from (can also used compress air at low volumn of say 50 psi).

If it is only a stuck valve u should be able to free it up thru the tappet galley or worst case heat the valve guide thru the ports in side of the block.
