Go ahead and skip lapping the heads to the cylinder
one time and you could find out what I found out(20
years ago), it makes a loud chirping noise telling you
that it must be taken apart and done correctly, in
other words lap them in and have peace of mind, when
you get the heads on and torqued hook up air pressure
120-130 PSI to the cylinders(spark plug hole with air
adapter) and make sure that no air leaks from around
the heads or valve seats. Just my two cents worth. Phil
