With ultra-smooth Grade A 356-T6 aluminum castings that are precision CNC-machined, these small block Chevy heads deliver awesome air speeds with super-efficient chamber designs to produce the power and torque
Head bolt torquerefers to the amount of rotational force that must be applied to the cylinder head bolts for a safe and secure connection either to the engine block or another cylinder head depending upon the engine. After the desired torque is reached, some bolts then require further rotation ...

Anyway, worn down cam lobes and bent push rods are two common failures in the cylinder head. Head gasket failures are another potential issue. No Chevy 454 is totally exempt from head gasket issues. However, it’s generally more common when overheating or running hot for extended periods. The...
Those are good starting places as far as simple bolt ons, but if you really want to make power you’ll want to consider doing work to the intake manifold, cylinder heads, and valve train. The cast iron intake manifold is heavy and doesn’t flow great. Adding a high-rise and high-flow...
This is also a sneak peek at one of the first releases of the cast iron LSX blocks with more bore (4.25 in max) and stroke (4.5 in max) and six head bolts (vs 4) circling each cylinder for more clamping pressure. That's 480 cid from a small block!!
