anybody buy/try these heads?

Engine Quests are just so...... amazing.

And not Chinese.
EQ's have a been represented well here on this site. They perform and have a good reputation. But if somebody was just looking to refresh their high mileaged magnum heads in their Dakota, Ram, Van, or whatever, they would be looking at replacing valve seals, perhaps springs, perhaps valve guides and even maybe exhaust valves, and maybe their whole head if they are cracked and they don't want to reuse them. These heads seemed priced right and are new, not remanufacted. Supposingly "thicker" where they normally crack. I just thought somebody from here may have tried them and have some feedback
