Are them springs stock replacement because I need some a little more heavy duty

Hey there. I am about to remove my car's 231 V6 and replace it with a BBC 454 V8. I have already replaced my rear coil springs. I haven't yet replaced the front springs, but I have been doing lots of research on the matter. Take a look at that Moog chart Qdub24 just posted. From what I've found, the Moog 5598 is a stock replacement spring for a V6 non-A/C G-body. The Moog 5600 is the stock replacement for a V6 car with A/C (which is what I have).

Compared to those, both Moog 5606 and 5608 would be an upgrade; these are the stock replacements for the V8 cars (with 5608 being the spring used in the 442 with A/C and the 307 V8, which is supposed to be a heavier engine than the Chevy 305). Compared to both of these springs, the 5610 is heavier duty still... which is why I plan to install 5610s in my car.

At least that's how I understand it all.
