Yeah all the retainers look the same so I quess it doesnt have them. I already have a good running Holley 650 so I'm gonna stay with that. The 318 is pretty quick right now in the Duster but I just want a little more until I build the 390. I'll look for a better intake and port match to my heads, do a mild port job on the heads and maybe try out the Comp XE274 cam and see how it is.

Hey maybe someone knows, the valves are stock type with the little ramp right before the seating surface, would it be of any gain to shave the ramp off the valves? I know performance stainless valves dont have this.

What you are talking about is called backcutting and will be beneficial on the intake valves. Mainly improves low lift flow. whether it is worthwhile on the exhaust is debatable. Some people say that leaving the ramp helps to impede reversion.
