Many engine builders prefer using cylinder head studs, as opposed to bolts, for their performance engine builds.
Cylinder head studs do offer some advantages, including higher clamp loads for more durability in high-horsepower applications. Studs can also safeguard your engine, putting the bulk of the fastener’s stress on the external nut side, which can avoid potential damage to the engine block.
If you’re looking to make the swap, the engine and cylinder head experts at Dart made this quick video that’ll show you some advantages of making the switch to cylinder head studs.
As part of its “Dart University” educational video series, Dart covers the basic purpose and benefits of cylinder head studs, and closes with valuable head stud installation tips.
The Dart folks made sure to address the different studs required for either an iron or aluminum engine block, and they stressed the importance of making sure you’re properly seating each stud to avoid damage to the stud and block.

For any performance engine studs are essential. BUT two main drawbacks. A when you torque plate hone the block for head studs or mainstuds you must use the studs in situ.
Ofcourse angle bolt main caps cannot use them on the outers but you can still on the inners.
B Main problem however in any tintop V8 you cannot remove the heads without removing the engine. Even many 4s and 6s. Them thar heads must come straight up the length of the stud.
A cast iron block really is good for about 3 retorques and then you are pulling threads. As an engine sealer for a budget race class I have seen a LOT of helicoils! As well as stripped out blocks at the track.
