what would be the best set of delivery valves for my 94 12v with the power i have

Probably 181s. Your makeing 50psi with that much fuel?

ya she is set at 50 just to be safe from blowing the head

your still playing on borrowed time at 50

the stock head is rated at 55PSI so im not woried

not so much the head its the headgasket

thats also rated for 55PSI

Where did you get that info from? I only ask because my head gasket blew at 40psi.

me and my buddie are in a 2nd year diesel mechanic program and know from experience and i red it in one of the diesel power mags a few months ago

Its usually not so much the hg blowing out as much as it is the head lifting becuase the bolts arent strong enough.
