you would have to retard the ignition timing to run pump, which would decrease any power gains u would see from the higher compression. 11.5 is the max i would go on pump but do what u like

You can run higher than 11.5 on pump...i wouldn't run 13.7, but with the race gas mixed in I think he will be fine.

If I read his setup right, it sounds like he's running 13.7 pistons PLUS "h. comp valves" (im guessing flat-faced valves). Which would put him close to 14:1. He didnt say wether he's running a thinner (.015") head gasket or not. Either way I wouldn't put pump gas anywhere near that motor.
