question about valve stem seals

im working on a 75 360 to put into my 71 duster
while I am prepping the motor im installing a new camshaft, intake and oilpan

I ordered a fell pro full gasket kit to make things easier and a comp cam camshaft kit aswell
both came with valve stem seals, the fel pro has positive intake seals and umbrella style exhaust seal

the comp cam kit came with 16 umbrella style seals that are nearly twice as tall as the taller positive intake seals

(couldn't find a decent part number on any of them)


which seal should I go with?


thanks
