Should I Sandblast My Heads?

[shovhd]

Is that the best way to clean up the heads before I send them to the machine shop? I've already removed the valves and springs.

Thanks

I thought they would bead blast them there as part of their service.
If you do, don't touch any of the machined surfaces.

most machine shops will emerse your head in a bath of chemicals that will leave them nice and clean.

X2, the machine shop should have something to clean them, if not I would just pressure wash them.

If their not rusty the chemical bath will clean them up just fine. If their very rusty the chemical bath doesn't clean them up very good so they'll need to be bead blasted first. I don't know of any machine shop that bead blasts them as part of the clean up procedure. Every one I've done they charged extra if they needed blasted. If you do blast them don't do the block or intake side.

Thanks everyone, guess I'll let the shop (as soon as I find a good one) take care of them.

i guess you could but like others are saying you can blast the flat surfaces or the ports might wear them to thin.
