I know this issue/question has probably been covered already but I can't seem to find the thread.
Anyways, as most do my slant head PK80 came with 2 head gaskets. I checked the piston/plug clearance with just one head gasket and my newly acquired NGK B6HS plug and there's no interference issues at TDC. Obviously just using 1 head gasket will raise the compression slightly which should give slightly better performance but that's not my motivation. Instead I figure 1 head gasket reduces the number of joints by one and so lessens the chances of a leak since the slant heads seem to be more prone to warpage.
What do the HT gurus say on the subject?
