Wow, I didn't think I would get more posts after I said I was going to just leave the Ace Grade 8's in there. I forgot to mention earlier that when I showed the original Grade 5 bolts to that engine builder, they said they looked fine and felt ok about me using them. Well, after all added posts about the NOT using the Grade 8's I installed, I've decided to remove the Ace Grade 8's and re-install the Grade 5's that were in there originally. Thanks for all the help
