Head Gaskets

It is a 2 piece valve. Your magnet won't stick to the head but it will stick to the stem. The valve is welded together about halfway up the stem. It has an Inconel head and stem half way up. This is the reason they are not recommended for a supercharged engine as they tend to fail.

all inconel valves are 2 piece,[that i know of] if they made the whole valve out of that material they would be to heavy, they spin the stem to ultra high rpm's and friction weld it to the head
