Super C Head Studs

Duane WI · Oct 22, 2016

I have had on and off again problems with the head gasket leaking on my Super C. I replaced the head gasket a few years ago and that fixed it but I noticed some of the studs head stretched and where not holding torque very well. I have tried re-torqueing a couple of times and that fixes it for a year or so but it always comes back. Went to change the oil today and noticed milky oil and the radiator was a low. The price of new studs is $15 each and I need 14. The newer versions of this engine just used bolts. I can get grade 8 bolts for a lot less than $15. Any reason I can't change over from studs to bolts? I would follow the torque specifications for the newer engines that used bolts.

Thanks, Duane

I dont see any reason why they would not work.

Bolts have less clamping force than studs which are also stronger. It is why hotrodders often replace head bolts with studs. My guess is newer versions use bolts for cost cutting like most car makers. The threads in the block deck are course while the nuts and upper half of the studs are fine. Not sure if earlier block holes can handle being torqued since they are designed for studs. Stuff that is torqued are usually fine thread.
