I went to the hardware store and got 6 grade 8 bolts the proper length . I ran a bottoming tap in as far as it would go before reinstalling the shaft with HD supports . I had to do this because I found that the shaft bolts had only engaged a couple of threads and one of them pulled .

Watch the length of the bolts used as well. Those holes have a depth of two inches, I used a 1 3/4 long bolt and chased the threads before putting them back on. You don't need a lot of torque on them. Torque spec is only 25 ft lbs. Don't go crazy with it.

Are you using original rockers/shafts or new aftermarket roller rockers of some sort?

Harland Sharps this time around but same applies for stock or aftermarket.

One watch out and something I encountered on my Harland Sharps.... Check the contact pattern of the tip the roller on the valve. If it's not pretty much dead nuts center, it will beat the guides out of the cylinder head. I ended up making spacers to correct this issue.
Longer bolt compared to stock is definitely required

I believe mine had stock bolts used , thus barely any thread engagement . I noticed the motor started to run weaker and valve train noise . When I went to check , the bolts were loose . upon retorquing , the back driver side did the "tighten then loose" pulling the top couple of threads out . I chased the threads , ran the bolt in as far as it would go and got bolts the correct length .
