I guess one of the motors Yates built isn't doing too well. Zzp says the clearances are too tight and the pistons are scrubbing the walls.

I talked to zoomer, they are done with it. Everything left has been spoken for .
I hate to be that guy, but is Yate's really all that? All I have to go off is what the Facebook mob says. I tend to ignore most of the talk about his business practices since it 95% of the people talking shit have never actually bought anything from him. Yates' seems to have some neat parts, but I have yet to see or hear anything about his success record. His engines LOOK hardcore, but will they run? He gets really defensive anytime somebody asks for 1/4 mile times, dyno results, or even just a video of a running engine. That sort of behavior does not make me inclined to buy a big ticket item like cylinder heads. That's just me. I hope somebody here will be able to set it straight.
