The last owner must have floated the valves, and the exhaust valves tapped the pistons. It must have happened early in the 3k miles that was put on the newly built motor, because carbon was already over the marks it made on the pistons. Any way, the bottom of the n42 was straight so i put new exhaust valves in the head. I went to put the cam back in, and it would not go through the last cam tower. Found out the top of head is warped. I have been contemplating shimming the tower because everything else is good.

I have a L28 with flat top pistons and stock boar. I also have mikuni triple dues carbs. Does anyone know what head i should use? I would like to keep the compression down so i can drive it on the street and use high test gas. It also has a mild cam (witch i don't have to use). Also the header ports are square that matched the n42 head exhaust ports that met its demise by the last owner. I also don't know if i can use those headers on say a p79 with round exhaust ports. Any help would be appreciated.
