No personal experience on Dino engines, per se, but I've replaced variety of (cylinder head, main cap, connecting rod, etc), bolts/studs on variety of engine blocks I've rebuilt, including Daytona, due to variety of reasons over past 4+ decades and imagine there are countless or at least millions of others who've done it too. Most I've ever needed were available either OEM or aftermarket, but some I had to have custom made-to-order.
I'm assuming you mean the studs for the heads? I've changed the studs and nuts on my L-series engine precautionary during a engine out service in 2020. The studs are readily available from the usual suppliers . They are made in improved material and methods and pricing is fair. I consider it a "worth while" job to do unless you know the history of the original studs and that they appear in good condition. On the L-series engine you will need to seal the studs with Loctite hydraulic sealer (Or similar brand) because the threads in the block enters into the cooling water gallery.
