Re: Help re cylinder head
This probably isn't relevant now as you are buying new studs, but one way to get hard metals like steel out of soft ones is to wait until the wife goes out and put them in the oven. The theory is that the soft metal expands more than the hard metal. I went for about 150C to get my clutch slave cylinder out. There is a danger that your valve seats etc. may come loose as well on a head though.
To drift new ones in I use a socket that is slightly wider than the stud and put a nut in the end to make it shallower. It will help you to hold the stud straight when hammering rather than smashing up your thumbs & fingers.
The extension bar allows you to see the angle that the stud is making with the surface of the head, ensuring it goes in straight.
Using a bigger hammer (even soft taps with a sledge hammer) in a controlled way for this type of thing is better than going mental with a hammer that is too light.
A bit of grease helps. HTH
