Ok. So I ordered the Edelbrock Aluminum heads with the 1.90/1.60 valves. I ordered the TFS Stage 1 cam but I am returning it. I am going to run the stock bottom end from a 1993. I called a cam company that builds them and they suggested a cam with a 110* lobe separation and up to a .575 lift (that's what the head springs are rated up to). The tech told me that I will not have a problem with the piston to valve clearance. I have been told to be careful with the 110 * lobe because EFI motors like 112* and up. Any thoughts on this?
