Ive never seen them before. they seem cheap but I'm not sure if they will fit the LT1. would you rust them and will they fit?

RE: aluminum heads for LT1
I've never heard of them before either. They seem to produce pretty good flow numbers, but you may have to take those with a grain of salt. Another thing is it doesn't look like the have LT specific heads, which means that although they would bolt up, you're whole engine cooling system would be thrown off due to the reverse cooling of the LT1.
You want to pay attention to flow around .400" since this is a good "mid-lift" area and that's where your valves spend most of their time. I would personally go with the AFR heads that you were origionally thinking about. Their quality control is great and they have a resounding reputation. They do everything right at AFR, and it's hard to find that at other places.
Something else you could think about is http://www.totalengineairflow.com/
They work on an exchange basis, so you send them your LT1 cores and they send you an assembled CNC ported etc. head that actually flows surprisingly well.
The benefit of getting the AFR heads over the Total Engine Airlfow package is aftermarket castings usually allow for more porting because they put metal in the appropriate places to allow for further porting that the stock heads sometimes do not allow.
