Also, antifreeze acts as a lubricant for the cooling system. I don't know if 15/85 is enough for the water pump and those things fail enough as it is.
Good luck on the OFHG! I just ordered that, valve cover gasket, eccentric shaft sensor, and a few other parts... have a long weekend ahead of me as well.

I'm also adding-in Water Wetter, which'll give a bit of additional protection to the components (and also increase thermal capacity/transferrence), but I've been looking at charts and various articles about the freezing points, and 40/60 water/antifreeze seems like the right choice for my circumstances. I'll see how my temps are at the track this summer, and I can adjust accordingly. It's not too expensive, either. Certainly cheaper than a warped block and head (yikes!).
Thanks for the input!
