cjm. Unless you have access to specialised tools,and equipment, and know what you are doing, it is best to take the cyl head to a machine shop and get them to do it properly. The head will have to be dismantled, cleaned, all parts inspected for wear,and cracks.
Then if the guides are to be replaced they are are usually pressed out and new ones installed and will need to be reamed for correct clearences. Valve seats will HAVE to be recut. The head may also need to be planed.
Some jobs are really better off being done by experts. I,ve seen many of these types of job that go wrong and then they still have to be taken to an expert, and it can also end up costing much more if you don't get it right the first time. With this sort of repair it is really a case of, what you pay for is what you get. Good luck.
