Ring end gap preference
Like to do some experimenting myself some day. I do have a nice junk block to fart around with. Nice little cracks from the lower headbolt holes right to water jacket.
I don't think they need a lot of oil, but do need steady pressure. I can't believe some guys will run a roller lifter with a splash lubed roller. I guess it's different for a race only motor. Sure wouldn't wanna idle it much, though.
To each his own, I guess.
