If using bolts instead of studs were better Packard would have realized that during their 35+ yeas of using studs. Then threads that go into the block are different from the threads that the nuts go on as they are "water seal" threads needed to keep the water in the block from creeping up the threads. Bolts are not made with those threads and if there were bolts, after removing and replacing them numerous times over a cars life the threads would wear slightly and leak some water.


Fred, thanks for your reply. My opinion is that studs are better than bolts, as the torquing force is pulling up on the studs where they screw into the block. Probably why Packard chose this method. However, studs make removing a head more difficult, sometimes it can get very involved.

You guys deal with all makes and years. How did other manufactures who used bolts instead of studs deal with the issues you have identified? Thanks.
