I just rounded the bowl some, a lil working of a path from the valve guide to the seat on the far side bowl, layed the ssr back and up the the straight wall a lil, just to the peak...barely anything done and very conservative.
Once the guide is slimmed/profiled and the straight wall to bowl is worked it should start to come to life.
the other thing is the gigantic sky jump on the stock int valve, dont now if there is a enough face to remove it all, but I bet if it wasnt there...there could be another 5'sh or more cfm thats already there.
once this port is mostly done, maybe a fresh perf VJ will be done....then test again..
Maybe a 11/32 guide and cut down nail head valve to try out on the bench.
