While I've seen a few poor smallport castings.... this one is a pretty good casting, with decent chambers, and pretty good port-bowl alignment. What it doesn't have is a good short radius..... on ALL of the bowls....

I've not been a fan of the Supertech kit. One reason....

Did you have to use Bigport (or Mercedes?) keepers? Was this customer also using used OEM valves, or Supertech valves?
I'm still debating whether to sell off my Supertech valves, especially (as noted in that topic linked above) that I would be using OEM keepers and retainers.
