A heads up about Engine Quest heads

so why doesn't a known company like Edelbrock or EQ make sure their heads are a true bolt-on OOTB??? Don't make sense to me, if a common machine shop can go over a head and correct the flaws, why not the manufacture????? That way the "fully assembled heads" are true bolt on.

I find it strange as well, especially with buying a built head. If the thing comes to you assembled, you shouldn't have to disassemble, correct, and reassemble to use. But oh well I guess that's just the game.
