Bought the car with a BTR stage 2 cam and .660 springs on 806 heads. When I pulled the heads to swap on a set of 243s I found this. Every piston is nicked, passenger side pistons nicked towards the rear of the car, drivers side pistons nicked towards the front. Posted closeups of the shallowest nick and the deepest.
I'm guessing it happened awhile ago because there was so much carbon buildup I couldn't even see the damage on the pistons until I cleaned them. Think they're savable?
I'm putting on a set of lightly ported 243s. The heads I pulled didn't have any bent valves so I guess it was fixed at some point. What would you use to clean up the gouges? It's odd, some look smooth and others are pretty jagged.
People notch pistons deeper than that. Are all the pistons the same? Might have been a poor attempt to notch them.
You know, it might be a poor flycut job. Every piston is cut on only the intake valve side, but the cuts are different depths. If someone did flycut them, I'd say it was their first time doing it.
