Bob;
Glad to hear that you got things worked out. FWIW, I had an Ashwamegh 25/2, (gone now, long story but it isn't a good one!!) - it had sleeves and four (plus the rockers) bolt heads. I'm in Ontario and do stock spare Indian gaskets for the 6/1's (as well as other sizes and parts) , I have a bunch of 'em here if you need one in the future. BUT, it's not usually the head gasket that causes leaking but instead the height the liner protrudes past the top of the cylinder deck. Too tall ands the gasket can't do it's job - no matter who make it. On some engines the lip that the liner sits on was not machined properly, causing the liner to stick up too far. Just a matter of popping the liner out, re-finishing the lip and re-seating the liner. If I hadn't just has an attack of Allen-zee-heimer I'd be able to remember the ideal height - maybe Hotater or someone else with the knowledge can chip in here.
