i don't think the ootb edelbrock valve job would be IN-adequate...just if someone were to prep a head really nice then there is the possibility of truing up the valve job and deshrouding.
also, the E-street heads were very recently only ~$1200.
so i guess one advantage with the edelbrock stuff is, look at autozone's website and see the 20% off code. I do see the 5090 head listed there. so order from autozone, or call jeg's and price match.
