Block Studs

Has anyone replaced Engine block studs? Do they even exist? Are they prone to failure?

Thank you.

 

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.
Best, Peter
