Changed head gasket cranks but won’t start

Hello, I sympathize with your situation but there's absolutely no way to know anything about what's going on unless you perform hands-on testing. Anything from improper engine timing to something not reconnected properly to some sort of engine performance issue that you didn't anticipate due to lack of fuel or spark or air could be occurring.
