Show off your small block.

I did install right out of the box. Smooth ports. Only bad thing I can say is no sort of instructions came with and the manifold and rocker rail threads strip out easy. Also had to get a smaller sparkplug hex size. The 11/16" socket won't fit had to go to 5/8" hex head.

I hope you'll provide an update after you run em for a while. Thanks for the feedback.
