So let me get this straight. You're saying that the performance gain of a 5-angle valve job is not worth the extra time (sparing no expense at the machine shop)? The gains seen between a 3-angle and 5-angle valve job are typically 6-7cfm per port (from personal experience on a flow bench), and all you have to do is simply request this from your machine shop. How hard is that? If you are sparing no expense it is definately worth looking into.
