That's the best thing, talk to your shop. We have better parts now so with a good set of 5/16" bolts may be all you need and may be the strongest path. Now, I just throwing out there, ask about getting the engine internally balanced. SilverbluePB had his engine let go. The crank broke between the front main and 1&5 main journal. That seems to be a common failure point. I've seen cranks broken like this on other forums. I believe Mark said he feels it's more of an issue on road race where the engine rpm is up and down, not so much an issue in a street or drag car. Again I'm not mentioning this from any of my experience or knowledge just passing it along.
One thing great about getting older. A life in prison sentence is less of a deterrence
