IMO - unless you are planning on the engine running 100,000+ miles standard cast rings will more than suffice and save a few bucks at the same time. It was not uncommon for the OEM type rings to run 100,000.




Standard cast rings do seat quick & last awhile, But they generate more drag/wear on the cylinders then a Moly plasma ring, so it robs some HP, i always run moly/plasma rings in my thrasher builds, they will seal up great with the right finish hone, & have less drag then a standard cast.
