[QUOTE="Cyborg, post: 107841, member: 3426"] The photos in post 11 look a little odd to me, but I'm not the resident expert. Maybe it just the photo, but the seat looks like it protrudes into the port more than normal. Usually just a small amount if any from what I have seen. As if the head was ported at one point and then the seat was replaced at a later date. Not that you are going to be racing it, so not worth worrying about flow, but is worth having a look at it if and when you pull the head off. [/QUOTE]
