Here is the valve springs and retainers that i ordered from Moneky wrench racing (I contacted them to see if i would have to get upgraded keepers and they informed me that the OEM keepers work just fine with the camshaft upgrade), i am still waiting for the cams to come in so i may start the process. There is also the gaskets for the lower intake manifold that i ordered as well from Amazon. Lower intake manifold was ordered from ebay at a very low cost.
