Default Crank seals to use with vacuum pump?

I have been running a moroso 4 vane vacuum, pump on my 346, but in that I am building a forged 383 at the moment, I was wondering if i should go to something else as far as front and rear seals (crank) and anything else?

My application is FI, 3.3L whipple looking for 800 rwhp/t or better

thx

check with a company called signal seals. the build alot of nascar/prostock high vaccum stuff. but usually the stock double lipped stuff works good.
