Garageguy6078 Follow stovebolt free-up formula,be sure valves not stuck. Could put it in road gear and rock it both ways. With that much marvel in it watch out for fluid lock,could bend a rod that way,a full quart between all cylinders is a lot. Wouldn't rush into pulling the engine it may surprise you and be OK .Done one setting after 10 yrs. still fine today was in 82.They're tuff if they weren't they would be stamped into little toyota's by now !!
