842 aluminum heads

[jg396]

I was wondering if anyone had any advice on 842 aluminum heads? I'm thinking about installing a set on a 375hp 396 motor that I'm building to put in my Camaro. Can a person use these heads and still be able to drive the car regularly (about 800 - 1000 miles a year). I'm just worried about building it and having them crack and having to find a set of 840's (which I already have but might sell to get 842's). Then also loosing the value of the 842's. Maybe I'm off, but I have just heads comments about them cracking. I'm looking to build it to around the stock specs (11:1 compression and so on). I don't drive the car hard or anything. Just concerned about the investment is all. Any of your opinions would be greatly appreciated.
