getting real old, I thought I would be finished by now.... Options

[bd1308]

so anyway i'm bolting the exhaust up and i notice that the studs are broken on one cylinder....so i need to replace the studs.....

dad got the MAPP torch out ( woah) and i told him too hot.
went and bought a propane torch, heated the head up till the flame went out (gust of air) so around 5 minutes for both studs...they wont budge

is it kosher to buy a (x)MM drill bit, chop off the stud to level and drill and tap out to (x+1)mm?

Are there any threads left on the stud? If so, put a nut on the stud, and using a ox-acetelyne torch, weld the nut to the stud. Wait for it to cool, and then use a socket to unscrew the stud. This can be done even if the stud is stripped. All you have to do is to get the nut over the stud and weld it on.

I have to agree with what Clay suggested .....I have done it many times! Once the nut is "welded" on, spray some kind of penetrating oil on the stud itself to cool it back off and try to keep most of the heat in the head. Also lightly tap on the end of the stud while it cools for about a minute, and then slowly twist the stud back and forth! Hopefully, it will come right out .
