just 1 question , if the heads flowed enough too make that 600 hp mark ,and it seems everyone still wants a better head my belief was that a stock block had about a 550/600 hp rating so it appears that this would be a street head any more would be full race and everyone knows we don't have blocks to chose from so I wound buy it and be happy for my daily driver and week end racer and we know its got to be cheap or 90% of us wont buy it so just what does it take to please everyone I'm sure they would build it if the demand was there .
