I have installed an early Miller, not a modern aluminum one, but they are externally the same. The hardest part is removing the stock studs, the rest is an easy bolt on. The new Miller kit is very complete, and is therefor easy to install. They perform very well, but do require a lot of spark advance in order to get maximum performance. The stock cam can be used but an OHV grind is best.
