I've got some supertech valve seals going into my b18a1 head anyways I've got the exhaust side on fairly easy. But for some reason the intake side us being a real bitch. Like it will go on sideways then I have to push on the side that's sticking up. I've got them all on. And they look pretty straight for the most part. They are a little scarred up nothing major. But I'm just worried they will leak when I put the head back on. I have Brian Crower valve guides BTW. I'm about to break down and just order OEM intake ones and take it to a shop. This is the second time I've bought damn valve seals!!!
