Oiling Question For Sanborn

fairly well versed with all the oil mods, have been doing them for quite sometime, however we have been using the Melling HV pump and so far had great success with it, our new motors is probably the most radical we have ever built, should i change the spring in the pump with the hemi style spring, not sure if i agree with higher pressure, have always prefered higher volume, this motor will spend its life in the mid 7's, large cubic inches, we dont usually turn them as hard, this is a 413cid, with extremely massaged Indy X heads....already mocked up several times, final assembly underway
thanks
Luke
