This is how I've been doing them for years and actually as per instructions in Seloc Marine Jet Drive book.
#1 @TDC...
Exhaust Valves 1,3,4,8
Intake Valves 1,2,5,7
Then >1 full engine revolution so #6 is now @ TDC...
Exhaust Valves 2,5,6,7
Intake Valves 3,4,6,8
I go 3/4 turn from zero lash...and call it a day.
PS. and yes the lifter is on the heel of the cam
