When you start to make more power with the stock engine you run the risk of having an engine failure.
There is a lot that goes into these new engine builds, we start by removing the cylinder head and inspecting it for any damage. The cylinder head is then completely dis-assembled by removing all valves, valve springs, guides and retainers. The 3 mating surfaces are machined for a nice smooth surface, the cylinder head is thoroughly cleaned, pressure checked and then re-assembled with new and improved bronze valve guides, viton valve oil seals, 8 new intake valves and 8 new exhaust valves.
To build the block, we either start with your stock block, a 2.4L LE5/LE9 block or a 3rd Gen Ecotec block core and then completely disassemble and fully clean it. The deck of the block gets fully machined to give a smooth mating surface for the cylinder head, the rotating assembly is then balanced, the crank journals are polished and the short block is then re-assembled, checking for tolerances along the way. With the short block assembled we then install the cylinder head on the short block using the new parts listed below -
