DING DING DING SOUND THE ALARM!...

I really wonder if you’re playing with fire running these fully built heads right out of the box. And I’m sure they’re work, but for how long? I guess for a budget build, sure send it. But if you got money in your bottom end, I’d be afraid to bolt on cheap heads and run them hard, but that’s just me. You gotta ask yourself, do you feel lucky, well do ya? :-). Bare castings built up with quality hardware sounds like the way to go with these.
