The gentleman selling those speedmaster big block heads. I’ve had a couple dealings with him and his dad. They inherited a junkyard several years back and are slowly parting things out and selling cars and such from there. Good people overall, but don’t expect to get great prices, the price you pay for most stuff, is gonna be towards the higher end of market price or more. Very rarely will you get a great deal price wise, but the items will be as described and they will deal to a point.
