Frankly, with the sort of music you're talking about, and the amp in question, I think most of the contemporary range is probably too much. Don't look at DC resistance alone, there's more to a pickup than a single number. For example, I used a black dog in my custom axe through a 5150-II to get absurdly heavy tones. You don't necessarily need the highest output pickup to get to the sort of gain levels you seek. True, I'm now using the aftermath, but that was because I wanted ultimate tightness from the pickup, which I got there.
The painkiller, aftermath or C-bomb might sound like they fit the bill for you if you only look at the descriptions and graphs, but frankly I think all of these are too hot/modern for your quoted styles. AlNiCo Nailbomb may be closer to it, but I think Philly Q hits the nail(bomb) on the head with his suggestion of Holy Diver. I don't think you'd be disappointed with that pickup!
My best advice, though: ask Tim! Drop him an email (address is on the BKP site). The guys there know their pickups better than any of us, and if you're specific about gear, what you want, don't want, like and don't like, and if you follow their advice, you'll almost certainly end up with the best pickup for your axe :)
Hope this helps,
Roo
