hey to all ,need info before install ,has anybody installed a ported & 3degree valve angle head on there speed 6 yet ,if so how did it perform , i had a spare complete head ,& just for the hell of it brought it to work because i had nothing to do & ported ,polished & cut valve angles , planning to get original cams re-worked to a mild street cam ,[note no BS this time ] .
