Update 2

We'll start this update with some pics of my storge of parts.

Here's my assistant.

Today I got a mechanics hammer and started pounding on the valves. Two came out and the other two the valve guides punched through

:shock: NOT what I planned. If any of you have a B 2871R head, email me.

Here are just a few pics of the tractor.

Here's some pics of the sunset.

Do any of you know what this steering wheel is off of?

Once again, feel free to offer advice, just don't say anything about not pounding on valves.

The head would have needed guides anyway. No lose, the machine shop will fix you right up.

As was mentioned, the head needs to go to the machine shop anyway and be magnafluxed = checked for cracks. I wouldn't go searching for a different head just yet. Wait for the machine shop to evaluate it first.

So you mean I didn't ruin it? I thought that the guide rested on a lip and that I pounded the guide though the lip.

They are press fit installed. And if the valves were stuck in them, there is a good chance they would need replaced anyway.

Needs exhaust valve seats anyway,

that head ahs been welded in the upper right . but once it gets soaked in the caustic hot tank then it will be inspected for cracks. you did
not have to pound on them valves plus u never ever do that. use a brass punch. once it moves a bit then you hit them the other way with lots
of lube and keep doing that back and forth thing.but these vaalves are all junk anyhow. they have a hard surface on the stems and you dont
want that beat up. all i am saying it is part of machine shop work and they have to drive the guides out anyhow for replacements. i can
see it needs valve guides and seats installed plus all new valves. your looking at around 700.00 for that job. another tid bit... when
working on rusted parts u need lots of time and patience, not a bigger hammer as they say.

When I worked in an automotive machine shop we would take a head like that and soak it in our hot tank
first. Then we would magnaflux it and if it didn't show any cracks with it that rusty we might bead
blast it to clean it up a bit more and maybe magnaflux it again just to make sure. After that probably
install new guides, of course they will need to know what the installed height of the guides should
be, then cut out for and install new seat inserts. From there we would take a light skim surface cut
on the head surface to make sure it is flat. After all that reface and reseat the valves and your head
will be as good as new. Sorry for the long post, just wanted to cover all the bases.

labeled.
Good luck, GG Wes

Good eye.

If the machine shop determines the head is repairable have them install new pushrod tubes for the
two intake pushrods.
