Valve spring compressor, and valve guide tools

OK, I posted a few weeks ago about an overhaul on a 1964 MF35 w Z134 4cyl. First time trying this with any engine.

So, from previous advice given, I found an engine hoist. Im looking for a stand. But I plan to split the tractor and bring the engine into the garage for the overhaul.

I pulled the head today. a few questions:
1. do I need a special valve spring compressor or could I get a universal type at the local auto parts that does the job?
2.The manual mentions special tools to replace the valve guides and says you can't tap them into place but need a specific tool fro pressing them....ideas?
3.What is a good way to go about cleaning the head and removing carbon buildup, and cleaning off old gasket? I was going to use a degreaser and power washer. For that matter, what are some good ways to clean off old gasket on other parts like thermostat housing.

Thanks for any help.
 
You are much better off to just take the head to a machine shop if you do not have the equipment.
 
I think your better off just sending the head to a machine shop.
They can clean the head up line new, check and replace the
guides and springs and do a valve job for you for not as much
as you would think. It would be money well spent.
 
Listen to what the other 2 said When you change guides the valve seat will be out of round with the new guide. Also if the head does not have insert type valve seats or even if it does new seats may be necessary to restore the correct valve spring height. Pick a good shop that does tractor work.
 
I'm a licensed aircraft mechanic and when I
overhauled my JD 1520 I took the head to a local
machine shop and did the rest myself.They should
also put in new hardened exhaust seats if it
doesn't already have them.A man has to know his
limitations.
 
As a licensed mechanic with over thirty years
experience, I agree with the other guys here. Take
the cylinder head to a good qualified engine
machine shop/rebuilder. Valve guides must be true
and square and seats will have to be replaced or
machined to match the new center of the valve stem.
A good cylinder head rebuild can be all the
difference between a great running engine or a very
poorly running engine. I wish you the very best
with your project !!

I don't think I have ever seen consensus on a forum. Thanks folks, Ill see what we have around here for that kind of work.
 
i would say if you have not found a good way to clean gasket material , then head rebuilding is totally out of the question.
the first place the head goes is in the dunk tank and is soaked in caustic, that removes everything.
don't think you will be spending 15000.00 on equipment to do a 500.00 head rebuild. actually it would be a lot more than that.
you would also need training on using the equipment. even being able to read a micrometer is a must. many many mechanics cant even grind valves nowadays. its machine shop work that requires machinest's that specialize in this sort of work.
