Changing the stock valve springs to racing valve spring (more durable)
Dura Tech valve springs installation (it took more than 2 hours to install this as it requires special tools so that there wont be any damage to the valves)
Sadly, i forgot to snap the picture during the camshaft installation, as i went somewhere, the process of installing the camshaft and the valve springs alone took more than 3 hours. The mechanic responsible for this installation is Mr Jai of Powerzone.
