Head gasket question

Last year I put a 1075 kit on my bike. I used the stock size head gaskets. Is there a set for the 1075 that I should have used? I'm thinking about putting the 1075 kit on my new bike and want to do it right the first time. (Imagine that) APE has a different part # for a 1075 head gasket set than a stock size. I assume it has a bigger opening. Last year when I started the motor with the 1075 kit and the stock head gaskets, I heard a couple of loud snaps. I'm guessing the valves hit the edge of the gasket. I'll probably get into the old motor this weekend and have a look. I also need to find some rings for the 1075 kit. Maybe if it rains I'll put the kit on the new bike before my trip to Canada to see Sandy. I'll need a little something extra to keep up with him. :laugh:

It shouldn't have been valves hitting the gasket. If a stock head wouldn't have its valves strike a stock gasket, then bore size shouldn't matter. I dunno if there's enough gasket poking into the cylinder to break off and cause trouble. Other threads having shown differing opinions on this.

hope this helps...Sam
