Default Head bolts for an EM1 engine

I need to replace the head bolts on my 1980 Honda Civic Wagon. It has a 1.5L EM1 engine. Apparently, it uses bolts called torque to yeild which have to be replaced once removed. Anyone know where to find some, or maybe there is some suitable substitution out there? Thanks!

Default Re: Head bolts for an EM1 engine

The bolts on the early Hondas are reusable but a back up is to replace them with grade 8 equivalent metric studs. The key to using the original bolts is to re-torque often during the first 10,000 miles.

Are you doing a complete rebuild or did a head gasket blow?
