Heres what the pistons look like. The dings on the exhaust side are minor and have not changed the surface area dimensions. I checked the heads on my bench by rotating the cams using my cam-holder tool. Good side (123) had ok valve clearance and appeared to have no problems. Bad side (456) confirmed prblem vaves on 5 and 6. I'm going to have the bad side machined and replace what is necessary...guides valves etc. Should I worry about the heads or just bolt it back up. Fortunately all the studs are solid. I'm trying to rationalize what else could have happed to the motor during this event as the PO was there and I wasn't. Whadayathink?
