So the cost that I posted are from talking to Machine shops in my area and summit or equivalent for parts.
I had my 675 heads done a few months ago because they were the original leaded gas valves and were pretty much done. They cost $759 and change to be re-done. Hindsight, I would have never redone them.
Here are the Machining cost.
130 Hot tank
185 Bore and Hone
145 Square the deck
150 freeze plugs and cam bearings installed
230 to balance the rotating assembly
150 line bore if main bearing are bad
That is the lowest cost I could find and not the place I have used in the past that I know does a good job. Not always best to pick the cheapest.
