As Jerry has stated stock valves are welded where the head meets the stem. These are one piece stainless steel valve. They are the same that we use in solid roller engines with up to 1000lbs open pressure and 8400 rpms. They are made for us by S.I. valves. Most companies do not have a 11/32 FE valve on the shelf so we have these custom made for our heads. You do not have to worry about the valves in these heads.
Thanks, Keith Craft
