If you plan of turning past 6K rpm, make sure that you use better springs than what GM used. They were the number one reason why L78 cars lost their engines. Not enought spring pressure to keep the valve in contact with the valve train. The valve would actually free fall shut eventually pounding the keepers through the retainer.
