okay go for a set of flat top pistons, deck the block, to decrease quench. Heads, hmmmm if new a set of edeldock performers matched with their performer camshaft. With the raised camshaft block you will need to probably run the shorter pushrods and to get your valve geometry right. I will have to look into the camshaft specs some more, what revs do you want to run in ? so being a street car I am picking you want to build plenty of torque with it. Right ?
