The Isky 185-G spring is just fine for what you're doing - install it at 2.00". What you didn't mention was size/weight of valves, what type of lifters, etc.. With just a .375 lift cam and 5500 redline, you'll have no problem with just about any valve gear you're using - 85 lbs on the seat is actually more than you'll need. You can easily get away with LZ springs - which at 2" are closer to 80 lbs. (I just checked some for Mac VanPelt today).

If you want a set of LZ springs, call Mac VanPelt -- the part number is 864-6513. They should be a bit cheaper than the 185-Gs . . . and should perform just as well for your application.
