So treat it like there are no marks, --better with head off, but find top dead center #1, make mark on crank gear straight up (paint, marker, etc), then with all plugs out watch valves in #1 cylinder (much easier with head off), if in chassis put in 3rd gear and rock car watching valves, when one closes and the other is opening rock it back and forth till is seems the valves are both open slightly and are even ---now make mark on cam gear straight down -------if marks match cam timing probably ok
make sure to put in neutral before using starter
