Thoughts,opinions wanted gas porting pistons

I'm assuming these are custom pistons.. I like CP in terms of "top of the heap". I do believe it will help you too. Be vey specific on the hone and cylinder finish too. I've seen the same engine (V8 5.9L modified tour) gain 40hp just by playing with cylinder finish with the same ring, same gap, same piston. The only differences were gaskets (replaced with same pcs) and the finish. Also, have you centered the head over the bores? I've seen some V8s that really seemed to wake up by centering the heads properly. What have you done with it in terms of dyno work? Cam phasing? BSFCs? Valvetrain dynamics? You're not looking for much, but the record holders I was mentored by had to really fight for those "last few". Also, is it an auto trans? There are tricks to lighten and tighten there that are worth some ET.
