depending on how fast you want to go there are two different opptions. you could go with 4 bolt billet caps, but requires some machining and is a little pricey. or you could go with 2 bolt billet caps, all that has to be done to get those on is to have the block align honed. i will going the 2 bolt billet route, that should be plenty good for some mid 11s.hope that helps ya.
