Best Bang for the Buck Head???

I haven't used them personally. I've read about stuff and I know the big block were reported to have issues but even with that instance the reports were not first hand and the shop is not one I'd call strongly competent. I commented at one point I'd like to see more published builds before I buy them. I stand by that.
Love the dyno with no water pump or accessories on it. The heads were not responsible for that extra horsepower...lol
