Comp 4771's are what most people use. They do require a lil grinding or cylinder head machining to fit. Most people grind the locator. It takes a few seconds and can be done with a bench grinder. You only need to grind an 1/8 inch "indention" in each one and then clearance the 2 on the center exhaust ports for head bolt/washer clearance.
Comp 4770's will not need any grinding/machining but they are a larger ID and will not fit as tight on the guides. This kinda defeats the purpose of using "locators".
Crane makes some (and I am sure other manufacturers do as well) that will work but not sure if they need grinding/machining as well.
