I'm not trying to step on anyone's toes but I think it is easy to say what's your engine worth to someone, but we all have our budgets.
If this is what you have the money for just get it in and check it out really well. Set it on a block the check the rail straightness, use the end gaskets to check there, look over the welds really good, check the clearance of the pickup to the bottom of the pan. If it doesn't meet your expectations send it back.
If you want to look at a mid priced pan check out these guys. this is who's pan I am running and also a few of my friends.
