FrankWest107 Posted August 2, 2015 Share Posted August 2, 2015 Thinking of changing the head on my ford model A engine to high compression for added power.The manufacturer of the head recommends replacing the old /existing head studs..Is that really possible?? After 80 years have not those studs actually become part of the block???Anyone have any experience with this??? Let me know before I try it.

HarryJ Posted August 3, 2015 Share Posted August 3, 2015 It ain't easy to remove old studs........The old ones are stretched and brittle....If you feel you can remove them; I would suggest you try....or you could retain a master machinist; get him to attempt it....Do it right while you have it down.

Restorer32 Posted August 3, 2015 Share Posted August 3, 2015 The studs have to be removed if the block is to be bored. It's done every day. Best to let an automotive machine shop do it. Link to comment Share on other sites More sharing options...
Curti Posted August 3, 2015 Share Posted August 3, 2015 I work on old Auburns, they don't have Cylinder head studs, but they do have water pump and intake / exhaust studs. I have a 95% success rate in removing the studs by heating the stud with a oxygen acetylene torch and applying bees wax to the base of the stud. Wait about 15 minutes then rock the stud back and forth with a vice grip. After it comes loose, remove it with a stud puller. The guys at the machine shop are not water walkers, one of them gave me this hint. Link to comment Share on other sites More sharing options...
Restorer32 Posted August 3, 2015 Share Posted August 3, 2015 95% is about right. Now and then you are gonna break one no matter how careful you are. Usually the spark wrench and some penetrant and patience does the trick. Link to comment Share on other sites More sharing options...
db17 Posted September 12, 2015 Share Posted September 12, 2015 I have a 29 Dodge with stubborn head bolts. I took the nuts off and socked bolts with oil for about month. Then screwed the nuts back on until they were flush with the top of the bolt, them welded them on. It worked for most of the head bolts. Good luck.

Guest Bob Call Posted September 12, 2015 Share Posted September 12, 2015 Use a mixture of acetone and auto trans fluid (50 - 50) to soak the studs. Apply for several days before trying to remove the studs. Get new studs made for this application. Try ARP to see if they make them. Link to comment Share on other sites More sharing options...

Get new studs made for this application. Try ARP to see if they make them.A scientific study was done and this was found to be superior to all marketed products.
