Piston Protrusion Above the Block Deck, & Head Gasket Thickness Verification
Channel: Lets Boost it
Date: 2021-11-18

In this short video, we confirm and verify that we have enough piston to cylinder head clearance, using our old 0.051" thick compressed head gaskets. In the previous video to this one, we measured and confirmed the piston protrusion above our machine block decks in our 408 boosted LS short block. With the gaskets in place and mocked-up we can see that we have enough clearance. I also verified that there is no interference ( piston to cylinder head )  as the heads were installed and torqued to spec and the engine was rotated through a couple of cycles with no interference.
