What happens here

The video highlights the custom features of the engine block. The cylinder heads are BRODIX castings, CNC ported by LME. The engine utilizes half-inch head studs and copper head gaskets for enhanced durability. Top-fuel hoops are machined into the heads and block. The valvetrain consists of Crower billet stainless shaft rockers, and the engine includes large spring pockets to accommodate better valve springs, allowing for high RPMs (up to 8,000 RPM). The previous stainless valves were 'tuliped' due to excessive RPMs, leading to an upgrade to titanium intake valves and Inconel exhaust valves with titanium retainers for improved performance and durability.

Goal: Showcase advanced modifications to the cylinder heads and valvetrain.
