it looks like the (recently replaced) head on my 92 2.3 pup is cracked. i am looking at my options and i came across these heads on ebay

the company seems reputable so i called them and the heads are made in china. anybody use one of these? they come with a 90 day warranty and i have been told that they have had no problems with them so far. i would not mormally look at something like this but the stock isuzu heads are pretty much crap and i cannot find a casting #4 or #5 head for sale anywhere. i just want to drive this old truck and not have the same problems everybody else is having.
