I'm just gonna toss this out there because I don't know how critical is is for aluminum heads but...

Those bolts are torque to yield and two different diameter bolts torqued to the same spec, are not even.

I understand. Albeit, the head is already cinched down entirely on its installation prior to all this. It’s not like I removed the stud and the corner of the head lifted. But there’s heat cycles to follow so who knows. If I cinch this down in the ballpark I think it will be fine. That’s with a prayer of course….

By the way I don’t think this bolt I bought from the pull out drawer at the local hardware store is TTY.

Gotta pull the header for assembly clearance either way so I’m working on that while I wait for special drill bit and tap. 27/64” bit and a 6” long 1/2x13 tap.

The diameter of the washer surface on the bolt was about 1mm bigger than the machined surface on the head. I used a bench grinder to take a little off the bolt washer so it fits. Glad I measured it

I'm looking to see if I can find a 1/2" stud. I could buy an entire kit but I bet with some searching I should be able to find a single comparable fastener.

Anyone think a 1/2" stud would be better than a bolt in this situation?

Honestly, these kits are cheaper than I thought. I'll probably spring for one just to get a fastener I know was made for the job.

Wait, someone just warned me about the Speed master quality

I’m gonna splurge for an ARP 351 stud kit. If I ever pull the head I can always change to a time sert back to 7/16 then I’ll have a complete ARP 351 stud kit for sale. If it holds it holds.

I have a stud kit on mine.

Lever even heard the engine [think] about a head leak.

I did a spark plug resistance test while waiting for parts and tools. Here’s the results. Autolite 3924 plugs with low mileage. Do these numbers look ok?

By the way, that one with the highest resistance is also that one that was darker than the others.
