Probably not necesary with our Iron head, you could check it with a strait edge and feeler guages. Perfect time for head studs

We will not reinstall a head without it being sent to the machine shop first. On average it takes .005-.010" to get them back in spec.

And yes very good time for studs.

No you won't have to do the block. And it depends on how much they take off the head. There is only two thicknesses. Stock and .020 marine. If they take less than .010 off, go with a stock gasket. More than .010 go with the marine

Even if they take 20 off as long as they reseat the valves it will be fine just swap to 20 thinner coppers on the injecters
