id be more worried about the valves and pushrods. You can sand down the high spots on the pistons

Going to change the 8 exhaust valves, no rods bent. What else should I worry about?

Lifters (at the rollers), and cam lobes if indicated.

Just curious why you decided to start it with the timing being off?

Dumb mistake, but I'd be a liar if I said I've never done stupid ****. It happens haha, I'd say sand the pistons down with paper, do a check on valves and push rods and put it back together. Maybe time It first this time haha

Dont plan on timing it with a light, it isn't a SBC. Will install heads roll the motor over and go with it.
