Preparing block for new head

[newshirt]

Is there a special treatment or method to prepare a block for a new Snyder head?

As a teenager, I once used a rusty paint scraper.

Now my redneck instincts tell me to use a circular wire brush (on an electric drill) for the top surface, and a rattail wire brush and compressed air for the stud holes. But won't that blast debris into the cylinders, valves, and water jacket?

After stuffing rags in the cylinders, I just go at it with a razor blade in a blade holder. It's tedious, but it works well. Your not making stuff fly all over the place that way.

But how do you clean out the stud holes? Won't that blow debris around?

Also, should I clean the tops of the pistons?

TAke off as much as you can with a stiff putty knife. Instead of a wire brush, I use one of those round paint remover things in the drill made out of some kind of plastic. Doesnt leave the marks a wire brush does. Sure clean the piston tops while you are at it. Blow lots of air to get the crud out.

If you are leaving the valves and manifolds in place.....take care to ensure carbon and crud does not go back down into the open intake valves especially, where upon when the engine starts the crud is sucked back into the cylinders, which might cause scoring.
You might find, that when you receive the head, the combustion chambers are very rough. Even a lot rougher that your present cylinder head. You might give consideration into polishing some of the roughness off, but be very carefull not to scar the sealing surfaces, or get carried away and destroy the CC characteristics of the combustion chamber.

After cleaning...note that Snyder's HC head may be thicker and require a different setting of the head studs. See the following thread: https://www.fordbarn.com/forum/showth...ht=stud+length

I use a shop vac and a scraper, so all the junk is sucked up as soon as I get it loose.

Stick with the scraper. To much chance of a small piece of wire from a brush getting stuck someplace.

To clean stud holes I ground four vertical grooves in a hardened bolt with the same threads. I ran the bolt down the stud holes with some WD40. The crud was be picked up in the grooves
