Can I reuse them or do I need to buy new one? Thanks. | | | | | Joined: Dec 2018 Posts: 2,450 'Bolter | | 'Bolter Joined: Dec 2018 Posts: 2,450 | Snowman 51 Never used a new headbolt. I wonder if you can buy a set of headbolt studs,I think you could get a better torque-up with studs. You would need to seal the block threads,could use a hard washer and high quality nut. | | | | | Joined: Feb 2000 Posts: 5,190 'Bolter | | 'Bolter Joined: Feb 2000 Posts: 5,190 | If the bolts clean up and look good, no reason you can't reuse them. If they are rusted and pitted, you might want to find another set. | | | | | Joined: Feb 2019 Posts: 4,472 AD Addict & Tinkerer | | AD Addict & Tinkerer Joined: Feb 2019 Posts: 4,472 | I just reused mine last year with no issues on my 235.

ARP has a kit P/N 155-4002. Kit for a F--d 427 SOHC 427. You end up with 4 extra short studs, washers & nuts but cheaper than purchasing open stock parts.

Fox, I understand we aren't talking tty bolts, I deal with them at work, designed to tight to low torque then a given angle of further rotation & they do stretch. Not saying 60 year old bolts aren't fine, however if you want to replace them studs look cool as well as more clamping force.

I'll probably have to make my own gasket, by using a conventional one as a template.
