Cylinder Head Rebuilding
Rebuilding a cylinder head brings valve work and head condition into the same conversation, rather than treating the gasket surface alone.

Cylinder heads
Cylinder Head Resurfacing
Head resurfacing addresses the cylinder head’s gasket face. It is a different decision from rebuilding the valves or machining the engine block.
View serviceValve Jobs
A valve job focuses on how valves meet their seats, not the flat surface where the head gasket seals.

Engine Block Boring
Block boring changes cylinder bore size and geometry. Plan the work together with the pistons and the subsequent honing requirements.
View serviceCylinder Honing
Cylinder honing concerns the bore’s final surface and dimensional requirements, with the piston and ring combination guiding the discussion.
View serviceEngine Block Decking & Surfacing
Block decking and surfacing address the block face that supports the head gasket, not the cylinder walls or the head itself.
View serviceCylinder Sleeving
Cylinder sleeving is a different repair conversation from simply boring a cylinder larger: it involves fitting a sleeve within the block.
View serviceCrankshaft Grinding
Crankshaft grinding addresses journal dimensions and surface condition. It removes material, unlike a polishing-only request.
View serviceCrankshaft Polishing
Crankshaft polishing concerns journal surface condition. It is not a substitute for correcting an unsuitable journal size through grinding.
View serviceLine Boring
Line boring concerns an aligned series of housing bores, commonly discussed around the crankshaft’s main-bearing housings rather than the cylinders.
View serviceConnecting Rod Boring
Connecting rod boring addresses the dimensions of a rod bore. Tell us which end needs work and the pin or bearing fit required for your build.
View serviceCNC machining
Lifter Bore Machining
Lifter bore machining is a focused block operation involving the lifter housings, separate from cylinder or main-bearing bore work.
View serviceCNC Engine Machining
CNC engine machining brings several distinct block and head operations into one request, including circular interpolation and thrust cutting.
View serviceCustom CNC Parts
Custom CNC parts start with the component you need and how it will be used. Bring a drawing or sample and the details of the parts it needs to fit.

Gas Engine Rebuilding
A gas engine rebuild is the whole-engine path: discuss teardown, machining and assembly together rather than ordering one isolated operation.
View serviceDiesel Engine Rebuilding
A diesel engine rebuild requires an engine-specific plan for the head, block and crank rather than a generic list of replacement parts.
