Engine Mod Help

I have a '72 Plymouth Valiant with a 225ci Slant Six. I am in the process of repainting it and would actually like to do some performance mods. I have found a site with plenty of mods for and was just wondering if anyone has any experience with how these engines respond and perform with mods. I have heard that they can do well but I was just looking for firsthand experience and knowledge.

Matt,
Sent you an email,

Short answer:

It's worth doing. All Slant Sixes are worth doing. And They run FOREVER.
