Stock vs hp Steet clutch discs
i'll echo the sentiment of veering toward a stock rebuild with a shift kit.
add a deeper pan for more capacity and a drain plug. you'll need a filter extension if the new pan doesn't come with one.
if you don't have it, part throttle kickdown is nice. they sell a kit for it.
personally, i'd go thru A&A for the parts. one stop shop for all the bits and they'll walk you thru it on the phone.
