On my end, part of the initial cost of the entire car, lol! They're stock 675 318 head with a .010 cut and a more performance oriented valve job than stock. But I'm starting on a set of iron heads that quoted for around an $800 to $900 outlay, but we're going to have to see what inflation is going to do for that. That's not including my time for what little home port work I plan on doing. There's quite a bit of machine work and parts for that, though.
