Stripped SBC Head Bolt Holes

Putting my heads on my 350 I stripped two of the head bolt holes. Both were where the short bolts go next to the exhaust ports. It would be an easy fix with timeserts or helicoils, but I don't think you can install those without taking the heads off and I don't want to take the heads off because I think more holes will be stripped when I put the heads back on.
I did see a post in another forum where someone suggested tapping the holes for 1/2 inch bolts and using some Oldsmobile 1/2 inch head bolts. Has anyone ever tried this or does anyone know someone who has?
Thanks.

Sure hoping someone can help me with this because I contacted Timesert and they said the head would have to be removed in order to use the timeserts.

The head will have to be removed and your fear may be a real one...
You may have to use a lot of heli-coils!

Probobly was in a hurry and forgot to chase the threads with a thread chaser. Which would remove all the gunk that can build in there. Hope a lesson was learned.

sounds like hes goin as tight as he can go...probably figured "well i had to put everything i had into to get them out, probably should do the same to put them in" 70ft lbs guy!!!! in 3 equal steps..or as equal as you can be...you can probably find the bolt sequence online if you look hard enough

Ya or used a impact gun.
Horsepower sells Engines and torque wins races.
