<div dir="ltr" data-setdir="false">The liner protrusion spec I mentioned in my previous email (.003" - .005") is right from the TR-4 Factory Workshop Manual. Obviously, this implies use of a stock factory head gasket. I used this same spec with the factory steel shim gaskets for 24 years in my race engines and never had a failure. If manufacturers of other head gaskets recommend a different protrusion spec, obviously go with their recommendation.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jack<br></div><div><br></div>
