Installing cylinder head bolts yourself

The reason for replacing the bolts immediately is that cylinder head bolts used to be mostly "normal" bolts. You can reuse those because a rigid bolt usually keeps the same length. Even after tightening firmly once, disassembling for repair, and finally reassembling. The disadvantage of rigid bolts is that they do not absorb the movement of the cylinder head. Combined with plastic head gaskets, the head gasket still gave some "spring". Nowadays, the so-called MLS (multi-layer steel) gasket is used in almost all engines, but it does not have this springiness. The use of angular tightening bolts solves this. These bolts are tightened until they are in the stretch area. While an engine is running, the cylinder head is subjected to high compressive forces due to compression and combustion pressure. The spring force of the angular tightening bolts keeps the MLS gasket sealing well.

Tightening such angular bolts requires precise craftsmanship; you should not tighten them beyond the manufacturer's prescribed torque. The tightening sequence is also very important here for an even distribution of the tightening torque across the head gasket.
