FYI, RabidScott, I'm a dyed-in-the-wool slant loyalist, and I'm sick and tired of V8 guys insisting that every slant should be replaced with a small-block (especially in a so-called slant six forum like this).
HOWEVER, I'm also sick of slant newbies asking how to make their stock slant a Honda-killer (usually on a limited budget). If you have to ask, you probably don't have the resources to do so.
I LOVE my slant, but if the goal is to beat up on your average, modern import, hopping-up a slant will leave most folks unfamiliar with slants VERY disappointed, and they end up swapping in a V8 anyway (or getting another car altogether). Making slants fast takes more time, money, experience, experimentation and patience than a V8 swap. Simple as that.
What most V8 guys don't seem to get is that making as much power as cheaply as possible isn't everybody's goal. People who love slants don't normally have that "never enough power" syndrome (Slantzilla and a few others excluded :) ). Some of just like being different. If I could figure out how to get that through the heads of the V8 pests who constantly insist on an engine swap, maybe they'd leave us alone for a while. But I doubt it.
But just because someone HAS a slant doesn't mean a slant is right for them. It takes a passion to work with these engines. My comment was to save the OP some time and effort if that's not the case. If it is, he's not going to get the answer in single forum post.
