I blew my head gasket about a week and a half ago in the evo. I brought it to metro engine right in arden hills. They saw the surface and asked me where the hell did this get machined before. I had no clue cause I bought the entire long block from ron at rs motors. After the head was dissasembled I got a call from metro and they said I had one bent exhaust valve, WTF I said. I just dynoed it a few days before at map and made crazy good power on the fp white. There was no power loss and the timing was dead on when i removed the timing belt. How the hell could I bend a valve, here comes the crazy part. I got another call from metro today and they said that all my exhaust valves will need to be replaced cause there was wear on all of them. This head had less than 12k on it when the headgasket blew. Also the valve seals that were removed from the head were the incorrect sized ones. They all had unusual wear on them. All in all Im pretty pissed right now cause I thought I would just have to have the head resurfaced and then slap it back on with some L19 headstuds and a oem mls head gasket. Here is the wear on the valve seals
