I forgot to mention that we tested an out-of-the-box Blue Thunder against 
my ported one, and found that my ported version had noticeable gains.   There 
is an easily rectified flaw in the design that causes four of the runners 
to flow worse than the other four.   The modifications raise up the bad ones 
to flow the same as the good ones, and the engine is much happier as a 
result.

Dan can elaborate more--or you can send your intake to Dave McLain, who did 
the porting work, and he can do it up for you.
