You mention "special" head bolts on early hipo engine. How do they differ than the "standard" bolts. Other than being "special"...

Standard 289 head bolts are normal "torque spec bolts. The "new" ones for sell with the gasket/bolt "kit" are torque to yield and have a "washer head" design like a Boss 302 head bolt. "I" refuse to use the torque to yield bolts.

Thank you for the replies.
I don't plan on this being a trailer queen. In fact we have been thinking of getting it to running condition and driving it as is for a bit. I think we would use a modern head gasket. We will be looking at the felpro and the Ford racing graphite gasket. Are all modern gaskets made to be right/left independent? We have another set that has a raised crush ring around them but the ring is block side down on the right and head side up on the left see the attached photo.

I would suggest ARP head bolts and know they're going to do the job.

You need to have the water jacket openings as you have them. Flipping a gasket to make the crush rings the same on both sides is almost 100% guaranteed engine failure. The ring itself doesn't really care if it's up or down once everything is torqued down.
