There was a set of 516s needing to be rebuilt on one of the Mopar Facebook pages for sale earlier this week I believe for $100.
Sounds like $100 too much. I throw 516 heads away when they come in my shop. That's all well and good if your customer has enough of a budget to spend $1200+ on new cylinder heads. Many do not. Before you say you'll spend that much on rebuilding stock heads...that all depends on where you're located and who's doing the work. I've had stock cast iron heads rebuilt and spent way less than I see a lot on here quoting. All depends on the end goal, but a pair of 516 heads can be made into very capable high performance heads that make good power.
