  • Cylinder head resurfacing?

    I'm rebuilding the head on my 79, seals, a bit of porting, etc. I've decked the jugs and am now ready to deck the cylinder head. My question is, is there any way to remove the front and back studs on the bottom of the cylinder head so I don't have to try and surface around them? I double nutted a studs and tried to remove it, but it didn't seem to want to come out. I'm sure the head is probably threaded and the studs are installed with thread sealant. I just wanted to check and see if someone knew before I potentionally broke something

    Thank guys

    My thoughts would be to heat the stud to break down the thread sealant and then try the double nut removal, if that doesn't budge, then use a pipe wrench to remove it. Fit new studs when reassembling, JAT

      I'm curious why you're decking either. If you have a warp outside spec, I can see it, but keep in mind that this will change your cam timing (retarding the cams) depending on how big a cut you make.

        Sorry I guess I should not say deck but just resurfacing. I always surface both sides before installing a new head gasket for proper sealing.

        I'll give the heat a shot and see if the budge; just worried about breaking them.

          If you are just trying to get a good mating surface for gasket seal AND you have no warpage then I would disregard any machining and just scuff the clean surface with a scotchbrite pad and use some Coppercoat. Doesn't take much to get a good gasket seal.

            Studs

            An old trick that I will share with you, and works especially good on NPT threads is: heat the fastener (stud) only. While hot, touch a candle (wax) to the hot stud melting the wax al over the stud. The stud will now come out.
