The heads bare aren't too bad, it's the rest that costs. There is a lot of work in these, plus the valves, rockers, guide plates.. I think the bare heads were 550.oo the rest puts it up around the cost of Eddys. These are custom built for the short block. My pistons sit a tad out of the bore and I need to use .050 gaskets to get the dynamic C/R down to 8.6 to 1.
