Help- cylinder wall marks- is it a problem?
Ok here is the deal, I just tore down the motor to add some ported and polished heads. My 107 kit has about 2500 miles so far. When I removed the old heads I noticed some marks on the cylinder walls. The front cylinder seems to have more marks then the rear. Is this something to worry about? The marks can't be felt with a fingernail.

The middle pic is disconcerting. 1 and 3 show some ghosting at the cylinder studs and oil drain passage but that is common.. More so on virgin cylinders than ones that have seen a bunch of heat cycles before boring. It's probably more prevalent on the 3.938 bores too. I'd be a little concerned about the cylinder finish.. looks like it was done with too fine a stone.. As the crosshatch is weak. I agree with Kirby, pull them. have them checked..
