[QUOTE="Ol'89r, post: 1397736, member: 17212"] It doesn't depend on what kind of valve you are going to use, it depends on the condition of the valve seat. The valve seat can look good to the naked eye but it can be pounded into the head unevenly. You can't tell that by just looking at it you can only tell by cutting the seat or lapping the valve. It's not recommended to lap the ti valves. If I were you I think I would find another PRO mechanic. ;) The cam caps do not interchange. Using cam caps from a different head could result in seizing your cam. The cam caps are line-bored for each individual engine. Also, if you are going to use stainless valves, you can't use the stock springs. The stock springs don't have enough tension for the heavier SS valves. That is why you have to buy the Kibblewhite spring kit when using the Kibblewhite SS valves. Using the wrong springs on SS valve can cause your valves to 'float'. Valves that 'float' have the possibility of hitting your piston. That can result in a very expensive problem. There again, I would recommend having someone with the proper experiences and equipment do your head. Unless you know how to cut the seats and have the equipment to do so, you are taking a big chance of messing up your head. Your cylinder can be replated. Check with Millennium Technologies.com. IMO, it's best to use the right stuff. Trying to save a little money at this time could cost you a whole lot of money later. [/QUOTE]
