I am getting one of Mace's stage 2 COMP cams for my ecotec and was wondering if Mace sell the 90lb springs and upgraded push rods?

We no longer sell 90lb valve springs due to the undesirable spring rates they have for these applications. Fortunately though we have 105lb valve springs which are suitable for your application, as shown in the link below http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/mace/Products/SPG601/SubProducts/SPG601 Please note that you would need suitable retainers to suit these springs to be able to achieve a recommended installed height of 1.8 inches, which are available separately as shown in the link below. http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/mace/Products/SPG604 Upgraded pushrods are not required with this cam, however we have heavy duty pushrods to suit in stock. The part number for these is PR601.
